Advanced-stage duodenal cancer in pregnancy.

This is a case report of a pregnant patient diagnosed with advanced-stage duodenal cancer in the second trimester. To the author's knowledge, there are no studies that describe the management of advanced duodenal cancer during pregnancy and this case highlights the importance of creating a multidisciplinary team and incorporating shared decision-making when discussing diagnostic workup and treatment options, including the use of cytotoxic therapy during pregnancy, with patients. This study will also discuss maternal and fetal outcomes after the administration of FOLFOX (leucovorin, fluorouracil and oxaliplatin) chemotherapy during the second trimester.

Synaptic architecture of a memory engram in the mouse hippocampus.

Memory engrams are formed through experience-dependent remodeling of neural circuits, but their detailed architectures have remained unresolved. Using 3D electron microscopy, we performed nanoscale reconstructions of the hippocampal CA3-CA1 pathway following chemogenetic labeling of cellular ensembles with a remote history of correlated excitation during associative learning. Projection neurons involved in memory acquisition expanded their connectomes via multi-synaptic boutons without altering the numbers and spatial arrangements of individual axonal terminals and dendritic spines.

Shared Decision-Making on Using a CDK4/6 Inhibitor plus an Aromatase Inhibitor for HR+/HER2- Metastatic Breast Cancer: A Podcast.

Shared decision-making involves patients engaging with their physicians to make informed decisions regarding treatment selection, a process that empowers patients and ensures that treatment decisions reflect their individual values and preferences. However, shared decision-making can be challenging to implement for various reasons, including time, staffing, or resource limitations at community practices and differences in patients' cultural backgrounds or health literacy. In this podcast, we discuss how to ensure that individual patients' needs and concerns are addressed, including an overview of different approaches for initial consultations, strategies for tailoring conversations based on a patient's background or health literacy, and trustworthy resources that can help improve patients' understanding.

Delayed hemorrhagic gastritis caused by immunotherapy in a patient With metastatic melanoma.

Pembrolizumab is a monoclonal antibody which targets the programmed cell death protein 1 (PD-1) receptor of lymphocytes. It is commonly used to treat many types of malignancies. Immunotherapy-related adverse events are relatively common and include pneumonitis, colitis and hepatitis.

Cardiomyopathy is associated with ribosomal protein gene haplo-insufficiency in Drosophila melanogaster.

The Minute syndrome in Drosophila melanogaster is characterized by delayed development, poor fertility, and short slender bristles. Many Minute loci correspond to disruptions of genes for cytoplasmic ribosomal proteins, and therefore the phenotype has been attributed to alterations in translational processes. Although protein translation is crucial for all cells in an organism, it is unclear why Minute mutations cause effects in specific tissues.

The diversity of O-linked glycans expressed during Drosophila melanogaster development reflects stage- and tissue-specific requirements for cell signaling.

Appropriate glycoprotein O-glycosylation is essential for normal development and tissue function in multicellular organisms. To comprehensively assess the developmental and functional impact of altered O-glycosylation, we have extensively analyzed the non-glycosaminoglycan, O-linked glycans expressed in Drosophila embryos. Through multidimensional mass spectrometric analysis of glycans released from glycoproteins by beta-elimination, we detected novel as well as previously reported O-glycans that exhibit developmentally modulated expression.
