Transcription factor EB (TFEB) activity increases resistance of TNBC stem cells to metabolic stress.

Breast cancer stem cells (CSCs) are difficult to therapeutically target, but continued efforts are critical given their contribution to tumor heterogeneity and treatment resistance in triple-negative breast cancer. CSC properties are influenced by metabolic stress, but specific mechanisms are lacking for effective drug intervention. Our previous work on TFEB suggested a key function in CSC metabolism.

Did the Covid-19 Pandemic Impact Time to Surgery, Length of Hospital Stay, or Discharge Location for Subaxial Cervical Spine Fractures Requiring Surgical Intervention?

Background: The COVID-19 pandemic disrupted healthcare systems across the United States resources were consumed caring for COVID-19 patients. Past research on trauma activations during COVID-19 has found changes to hospital length of stay and discharge locations. Subaxial spine fractures are potentially debilitating injuries that require timely surgery and extensive rehabilitation.

Phenotypes of Pelvic Organ Prolapse.

Importance: The Pelvic Organ Prolapse Quantification (POP-Q) stages do not correlate with symptoms or characterize important prolapse subtypes.

Objectives: We hypothesize that clinically meaningful prolapse "phenotypes" utilizing POP-Q measurements can be defined. The primary aim was to define the phenotypes and their frequency.

The Role of Transbronchial Cryobiopsy in the Detection of Pulmonary Graft-versus-Host Disease.

Introduction: We investigated the incidence of chronic pulmonary complications in allogeneic hematopoietic cell transplantation (HCT) recipients and analyzed the role of transbronchial cryobiopsy (cryoTBB) as a tool to determine the nature of pulmonary changes and to guide clinical decisions.

Methods: Patients who survived at least 6 months post HCT were included in the study. Pulmonary functional tests (PFTs) were performed in all patients as a screening tool.

Cell non-autonomous signaling through the conserved C. elegans glycoprotein hormone receptor FSHR-1 regulates cholinergic neurotransmission.

Modulation of neurotransmission is key for organismal responses to varying physiological contexts such as during infection, injury, or other stresses, as well as in learning and memory and for sensory adaptation. Roles for cell autonomous neuromodulatory mechanisms in these processes have been well described. The importance of cell non-autonomous pathways for inter-tissue signaling, such as gut-to-brain or glia-to-neuron, has emerged more recently, but the cellular mechanisms mediating such regulation remain comparatively unexplored.
