Using Tap Water for Enteral Tube Flushes.

Background: Enteral feeding tubes, used in patients who require enteral nutrition or medication, require flushing between medications and feedings to maintain patency. Various types of water can be used to flush enteral feeding tubes, which raises the question of which type of water is best supported by evidence.

Purpose: The aims of this quality improvement project were to examine the evidence on the use of tap water instead of sterile water for enteral tube flushes and to implement the use of tap water as a safe, cost-effective alternative to sterile water at a multisite oncology institution.

Gestational trophoblastic neoplasm: Patient outcomes and clinical pearls from a multidisciplinary referral center.

Objectives: To describe clinical outcomes and pearls for patients with gestational trophoblastic neoplasm (GTN).

Methods: Patients with GTN treated at a referral center from 1/2006 to 12/2022 were included. Clinical characteristics, World Health Organization risk score (low-risk 0-6, high-risk ≥7), and treatments/outcomes were evaluated using summary statistics, stratified by initial treatment at a referral center versus locally.

Decreasing Premedication for Blood Transfusions: A Quality Improvement Project.

Background: Premedication administration to patients who are to receive blood transfusions continues despite evidence of a lack of benefit when given to prevent febrile nonhemolytic or mild allergic transfusion reactions. Reviews of ordering practices and staff surveys on an adult inpatient hematology-oncology unit in our multisite oncology medical center indicated a lack of standardization and overuse of premedication in blood transfusions and a lack of knowledge of when it was appropriate to use premedication.

Methods: A literature search was performed, and the evidence led to a proposal for a quality improvement (QI) project focused on development of an evidence-based algorithm to guide clinicians in when to administer which premedication, development of clear documentation for premedication plans, integration of the documented premedication plans into electronic orders for blood products, and staff education.

Convergence, plasticity, and tissue residence of regulatory T cell response via TCR repertoire prism.

Suppressive function of regulatory T cells (Treg) is dependent on signaling of their antigen receptors triggered by cognate self, dietary, or microbial peptides presented on MHC II. However, it remains largely unknown whether distinct or shared repertoires of Treg TCRs are mobilized in response to different challenges in the same tissue or the same challenge in different tissues. Here we use a fixed TCRβ chain FoxP3-GFP mouse model to analyze conventional (eCD4) and regulatory (eTreg) effector TCRα repertoires in response to six distinct antigenic challenges to the lung and skin.

Heart failure related to contemporary breast cancer treatment.

This article addresses cardiotoxicity in patients with breast cancer who are treated with anthracyclines and/or anti-human epidermal growth factor 2 (HER2) therapy, namely doxorubicin and trastuzumab. Development of concise clinical guidelines for chemotherapy-induced heart failure is ongoing. Through identification of specific risk factors and clinical predictors of cardiotoxicity, clinicians are able to better understand and define effective monitoring strategies and optimize patient care.

Caring for patients with life-threatening hemoptysis.

Life-threatening hemoptysis (formerly called massive hemoptysis), though relatively uncommon, imposes significant mortality risks. This article discusses the etiology, clinical presentation, assessment, treatment, and nursing interventions to promote effective clinical management of patients with this condition.

ChromaFold predicts the 3D contact map from single-cell chromatin accessibility.

The identification of cell-type-specific 3D chromatin interactions between regulatory elements can help to decipher gene regulation and to interpret the function of disease-associated non-coding variants. However, current chromosome conformation capture (3C) technologies are unable to resolve interactions at this resolution when only small numbers of cells are available as input. We therefore present ChromaFold, a deep learning model that predicts 3D contact maps and regulatory interactions from single-cell ATAC sequencing (scATAC-seq) data alone.

Reducing Tubing and Device Misconnections.

Purpose: The aim of this quality improvement (QI) project was to explore prevention strategies to reduce tubing and device misconnections that cause patient harm and death. Practicing evidence-based techniques can improve rates of nursing-sensitive indicators, such as central line-associated bloodstream infections, and increase patient safety.

Methods: Our nursing quality management team reviewed internal quality data and found 11 reported misconnections.

Increasing Patient Access to Medical Cannabis Requires Federal Legislation.

Marijuana's Schedule I classification remains an obstacle.

Activation of STING in Response to Partial-Tumor Radiation Exposure.

Purpose: To determine the mechanisms involved in partial volume radiation therapy (RT)-induced tumor response.

Methods And Materials: We investigated 67NR murine orthotopic breast tumors in Balb/c mice and Lewis lung carcinoma (LLC cells; WT, Crispr/Cas9 Sting KO, and Atm KO) injected in the flank of C57Bl/6, cGAS, or STING KO mice. RT was delivered to 50% or 100% of the tumor volume using a 2 × 2 cm collimator on a microirradiator allowing precise irradiation.

Best Practices in Pediatric Oncology Pain Management.

Pediatric oncology patients are vulnerable to pain that may be caused by the disease or its treatment, and this symptom can be challenging to manage. This article focuses on the importance of pain control, pain assessment and treatment, and special considerations in pediatric oncology pain management, including preparing children for painful procedures and the family's role in managing pain.

Self-supervised denoising of Nyquist-sampled volumetric images via deep learning.

Purpose: Deep learning has demonstrated excellent performance enhancing noisy or degraded biomedical images. However, many of these models require access to a noise-free version of the images to provide supervision during training, which limits their utility. Here, we develop an algorithm (noise2Nyquist) that leverages the fact that Nyquist sampling provides guarantees about the maximum difference between adjacent slices in a volumetric image, which allows denoising to be performed without access to clean images.

Principles of regulatory T cell function.

Regulatory T (Treg) cells represent a distinct lineage of cells of the adaptive immune system indispensable for forestalling fatal autoimmune and inflammatory pathologies. The role of Treg cells as principal guardians of the immune system can be attributed to their ability to restrain all currently recognized major types of inflammatory responses through modulating the activity of a wide range of cells of the innate and adaptive immune system. This broad purview over immunity and inflammation is afforded by the multiple modes of action Treg cells exert upon their diverse molecular and cellular targets.

CE: Tumor Lysis Syndrome: An Oncologic Emergency.

Tumor lysis syndrome is an oncologic emergency caused by the release of intracellular material, such as potassium, phosphate, and nucleic acids, into the bloodstream from the disintegration (lysis) of tumor cells. This condition, which is characterized by electrolyte imbalances, can be life-threatening, causing arrhythmias, seizures, acute kidney injury, and multiple organ failure. The prevention and treatment of tumor lysis syndrome requires immediate recognition of patients at risk for its development.

Spiritual Care as a Core Component of Palliative Nursing.

Spirituality is one aspect of the human experience that is unique to each person and may become especially important in the face of life-threatening illness. While evidence supports the need to address spirituality as part of holistic palliative care nursing, it is hoped that "spiritual care" will not become another item on nurses' to-do list, but rather will be part of nurses' everyday lives and nursing practice. Taking time to assess personal needs, and consciously connecting to meaning, hope, and peace, can support nurses' return to the deeper roots of nursing.

Addressing CAUTIs with an External Female Catheter.

Background: Catheter-associated urinary tract infections (CAUTIs) can lead to complications that prolong hospital stays and result in patient discomfort as well as increased health care costs and mortality. At our academic medical center in New York City, in 2016-17, 21 of 87 CAUTI cases (24%) were in bedbound female patients in whom indwelling catheters were used for incontinence. Although condom catheters were available as an alternative to indwelling urinary catheters for male patients, there was a lack of effective products for female patients.

The role of arts-based curricula in professional identity formation: results of a qualitative analysis of learner's written reflections.

Background: Professional identity formation is an important aspect of medical education that can be difficult to translate into formal curricula. The role of arts and humanities programs in fostering professional identity formation remains understudied. Analyzing learners' written reflections, we explore the relationship between an arts-based course and themes of professional identity formation.

Integrating Palliative Care into Nursing Care.

The need for palliative care in our health care system has exponentially increased in the past few years as a result of the COVID-19 pandemic, the aging population, and the increasing number of people living with serious illnesses. While nurses play a critical role in delivering palliative care, many lack confidence and knowledge, causing practice gaps in the clinical and psychological management of seriously ill patients. The collective burden of the pandemic has demonstrated the importance of palliative care education and training, specifically in communication, symptom management, and continuing education.

A nuclear cAMP microdomain suppresses tumor growth by Hippo pathway inactivation.

Cyclic AMP (cAMP) signaling is localized to multiple spatially distinct microdomains, but the role of cAMP microdomains in cancer cell biology is poorly understood. Here, we present a tunable genetic system that allows us to activate cAMP signaling in specific microdomains. We uncover a nuclear cAMP microdomain that activates a tumor-suppressive pathway in a broad range of cancers by inhibiting YAP, a key effector protein of the Hippo pathway, inside the nucleus.
