The growing population of older adults emphasizes the need to develop interventions that prevent or delay some of the cognitive decline that accompanies aging. In particular, as memory impairment is the foremost cognitive deficit affecting older adults, it is vital to develop interventions that improve memory function. This study addressed the problem of false memories in aging by training older adults to use details of past events during memory retrieval to distinguish targets from related lures.

Objective: DESTINY-Breast03, a randomised, phase 3 trial, evaluated trastuzumab deruxtecan (T-DXd) versus trastuzumab emtansine (T-DM1) in patients with human epidermal growth factor receptor (HER2)-positive unresectable and/or metastatic breast cancer who progressed on or after treatment with trastuzumab and a taxane. At the current data cut off overall survival analysis, T-DXd demonstrated a substantial improvement in overall survival over T-DM1. This secondary analysis use of DESTINY-Breast03 aimed to further evaluate the treatment differences using quality-adjusted survival time without symptoms or toxicity (Q-TWiST) methods.

Research on emotion regulation often focuses on cognitively effortful self-regulation strategies, but exposure to stress has been shown to interfere with the underlying mechanisms supporting such processes. Understanding alternative strategies that potentially bolster emotion regulation under stress is an important topic of investigation. Two potential alternatives involve everyday occurrences of social processing and memory recall.

Article Synopsis
  • PFAS are long-lasting chemicals found in various products and are prevalent in the environment, leading to potential health risks, including reduced reproductive success and immune effects in birds.
  • Research on Northern bobwhite quail exposed to PFAS showed that these substances can accumulate in their brains, with males generally having higher concentrations than females, except for one specific PFAS.
  • The study also found that exposure to certain PFAS can influence the accumulation of others, indicating complex interactions that need further investigation to understand their impact on bird health.

Creative divergent thinking involves the generation of unique ideas by pulling from semantic memory stores and exercising cognitive flexibility to shape these memories into something new. Although cognitive abilities decline with age, semantic memory tends to remain intact. This study aims to utilize that memory to investigate the effectiveness of a brief cognitive training to improve creative divergent thinking.

Background: The majority of junior doctors in the UK do not proceed directly into specialty training after completing mandatory foundation training but instead take a year out of training. A common post undertaken during a year out of training is a clinical teaching fellow (CTF) role which is used to provide undergraduate medical student teaching. There is only a small amount of literature available regarding CTF posts, and very little of this explores experiences or reasons for taking up such as post.

Article Synopsis
  • The study explores the use of Bayesian borrowing (BB) methods to improve the estimates of treatment effectiveness by enhancing an external control arm constructed from real-world data for patients with first-line non-small-cell lung cancer (NSCLC).
  • It examines the overall survival rates of patients treated with chemotherapy plus cetuximab compared to a constructed external control using historical trial data, revealing that BB provided more precise hazard ratio estimates than the matched patients in the randomized controlled trial (RCT).
  • Challenges were encountered in replicating overall survival estimates with the external control arm, attributed to factors like unmeasured confounding and variations in treatment timelines, highlighting how BB can refine effectiveness estimates and reveal biases when external data sources are suitably applied.

Associative memory refers to the ability to form and remember associations between individual pieces of information rather than memory for a single object or word. Encoding associations in memory tends to be a more difficult task than item (only) encoding, because associative memory requires encoding multiple items as well as the specific links amongst the items. Accordingly, researchers have worked to identify interventions and strategies to reduce the effort and neural resources required for successful associative memory processing.

Schemas allow us to make assumptions about the world based upon previous experiences and aid in memory organisation and retrieval. However, a reliance on schemas may also result in increased false memories to schematically related lures. Prior neuroimaging work has linked schematic processing in memory tasks to activity in prefrontal, visual, and temporal regions.

Biosolids are rich in organic matter and other nutrients that contribute to environmental and agricultural sustainability by improving soil textural and biological properties and enhancing plant growth when applied to agricultural crops. Land application of biosolids encourages resource recovery and circumvents drawbacks associated with landfilling or incineration. However, biosolids contain numerous chemicals at trace levels, and quantitative analysis of such mixtures in this complex matrix is crucial for understanding and managing application risks.

The development of fluorine-free firefighting foams has been proposed as a way to reduce the adverse environmental consequences of foams containing per- and poly-fluoroalkyl substances. While there are likely fewer environmental and ecological concerns with these new fluorine-free foams in terms of persistence and bioaccumulation, it is prudent to evaluate the ecotoxicity of these fluorine-free foam products given the absence of data. Oral chronic drinking water exposure studies on adult pairs of northern bobwhite quail (Colinus virginianus) were conducted with a short-chain fluorinated and a fluorine-free foam: Buckeye Platinum Plus C6 and National Foam Avio Green KHC, respectively, at three exposure concentrations (0.

Previous work has suggested unitized pairs behave as a single unit and more critically, are processed neurally different than those of associative memories. The current works examines the neural differences between unitization and non-unitized memory using fMRI and multivoxel analyses. Specifically, we examined the differences across face-occupation pairings as a function of whether the pairing was viewed as a person performing the given job (unitized binding) or a person saying they knew someone who had a particular job (non-unitized binding).
