Introduction: Nursing research is an integral part of nursing science and essential for evidence-based nursing practice. Research conducted by nursing scientists employed at university hospitals is shaped by the specific prevailing conditions. It is largely unclear to what extent these nursing scientists are engaged in research and which difficulties they have to face.

The ventral midline thalamus, including the reuniens and rhomboid (ReRh) nuclei, connects bidirectionally with the medial prefrontal cortex (mPFC) and hippocampus (Hip), both essential for memory processes. This review compiles and discusses studies on a role for the ReRh nuclei in the system consolidation of memories, also considering their potentially limited participation in memory retrieval or early phases of consolidation. It also examines scientific literature on short- and long-term plasticity in ReRh-mPFC and ReRh-Hip connections, emphasizing plasticity's importance in understanding these nuclei's role in memory.

Article Synopsis
  • Dorsal closing-wedge calcaneal osteotomy (DCWCO) is a surgical treatment for persistent heel pain due to Haglund exostosis after conservative treatments have failed, but its impact on everyday foot function is not fully understood.* -
  • A study involving 120 patients (ages 17-77) showed significant reductions in heel pain and disability scores at 6, 12, and 24 months following surgery, although there were also reported adverse events.* -
  • Despite improvements in pain and function, no significant correlation was found between changes in foot biomechanics (like the Achilles tendon moment arm) and patient-reported foot function scores.*

Loss of proteostasis is a hallmark of aging that underlies many age-related diseases. Different cell compartments experience distinctive challenges in maintaining protein quality control, but how aging regulates subcellular proteostasis remains underexplored. Here, by targeting the misfolding-prone Fluc luciferase to the cytoplasm, mitochondria, and nucleus, we established transgenic sensors to examine subcellular proteostasis in Drosophila.

Objective: The quality of the relationship between persons with dementia and family carers influences health and quality-of-life outcomes. Little is known regarding those at higher risk of experiencing a decline in relationship quality, who could potentially benefit the most from interventions. We aimed to identify these risk profiles and explore the underlying factors.

Background: Dementia with Lewy bodies (DLB) is the second most common age-related neurocognitive pathology after Alzheimer's disease. Animal models characterizing this disease are lacking and their development would ameliorate both the understanding of neuropathological mechanisms underlying DLB as well as the efficacy of pre-clinical studies tackling this disease.

Methods: We performed extensive phenotypic characterization of a transgenic mouse model overexpressing, most prominently in the dorsal hippocampus (DH) and frontal cortex (FC), wild-type form of the human α-synuclein gene (mThy1-hSNCA, 12 to 14-month-old males).

Background: The growing use of mobile health applications (apps) for managing diabetes and hypertension entails an increased need to understand their effectiveness among different population groups. It is unclear if efficacy and effectiveness trials currently provide evidence of differential effectiveness, and if they do, a summary of such evidence is missing. Our study identified to what extent sociocultural and socioeconomic inequalities were considered in effectiveness trials of mobile health apps in diabetic and hypertensive patients and if these inequalities moderated app effectiveness.

As the population ages, it is essential that professionals across disciplines have experience and competence working with older adults. Though experiential learning opportunities have been extensively documented as a tool to accomplish this goal, student engagement in gerontology research has not been examined in detail. This participatory case study highlights the perspectives of undergraduate student researchers involved in a hands-on pilot research study that explored connections between cognitive, physical, and everyday function in midlife and older adults while testing the feasibility of a mobile app for early detection of cognitive decline related to Alzheimer's disease and related dementias.

Although the health benefits of behavioral interventions for older adults are well studied, research focused on intervention acceptability in older adult populations is less established and is needed. This mixed methods study investigated older adults' perceptions of training interventions. Community-dwelling older adults ( = 41) were randomized into three groups (cognitive, physical, and exergame) and completed 20 in-lab training sessions over 10 weeks.

Germ cell tumors (GCT) are the most common solid tumors in young men of age 15 - 40. In previous studies, we profiled the interaction of GCT cells with cells of the tumor microenvironment (TM), which showed that especially the 3D interaction of fibroblasts (FB) or macrophages with GCT cells influenced the growth behavior and cisplatin response as well as the transcriptome and secretome of the tumor cells, suggesting that the crosstalk of these cells with GCT cells is crucial for tumor progression and therapy outcome. In this study, we shed light on the mechanisms of activation of cancer-associated fibroblasts (CAF) in the GCT setting and their effects on GCT cells lines and the monocyte cell line THP-1.

Sleepwalking and related parasomnias result from incomplete awakenings out of non-rapid eye movement sleep. Behavioral episodes can occur without consciousness or recollection, or in relation to dream-like experiences. To understand what accounts for these differences in consciousness and recall, here we recorded parasomnia episodes with high-density electroencephalography (EEG) and interviewed participants immediately afterward about their experiences.
