The Evolving Role of the Oncology Nurse in the United States of America-A Survey Exploring Their Perspective.

Background: The role of the oncology nurse has evolved since the COVID-19 pandemic to continuously meet patient needs, resulting in an increased virtual presence. However, there is little information about whether these roles have continued since the pandemic and how it is affecting nurses.

Methods: The aim of this study, conducted via an electronic survey questionnaire, was to examine the perspective of oncology nurses in the United States of America regarding how their role has changed, the adaptation to telehealth, challenges, and needs.

Changes in Skin Cancer-Related Behaviors, Distress, and Beliefs in Response to Receipt of Low- to Moderate-Penetrance Genetic Test Results for Skin Cancer Risk.

Little is known about the impact of low- to moderate-penetrance genetic testing for skin cancer, which is a promising approach to skin cancer prevention. To address this deficit, we conducted an analysis comparing changes in skin cancer-related behaviors, distress, and beliefs measured at a baseline and twice after the receipt of skin cancer precision prevention materials containing risk feedback (higher or average risk) among 568 non-Hispanic White (NHW) and 463 Hispanic participants. Regression analyses identified decreased average weekend hours in the sun (β = -0.

The Role of Radiation, Immunotherapy, and Chemotherapy in the Management of Locally Advanced or Metastatic Cutaneous Malignancies.

Introduction: Skin cancer impacts a significant proportion of the population. While surgical management is often the mainstay of treatment, advanced or metastatic cutaneous malignancies require additional local and/or systemic therapies.

Methods: A review of the literature was performed studying the use of radiation therapy, chemotherapy, and immunotherapy for locally advanced or metastatic cutaneous malignancies.

Declining Clinical Utility of Tools for Predicting Sentinel Lymph Node Biopsy Status: A Single Institution Experience from 2000 to 2021.

Introduction: Clinicopathologic data-based sentinel lymph node (SLN) prediction models are used to select patients with melanoma for sentinel lymph node biopsy (SLNB). However, the temporal performance of these models is unknown. Therefore, we investigated whether the performance and clinical utility of the Melanoma Institute of Australia, Memorial Sloan Kettering Cancer Center, and Friedman et al.

Correlation Between Disease-Free Survival Endpoints and Overall Survival in Elderly Patients with Early-Stage HER2-Negative Breast Cancer: A SEER-Medicare Analysis.

Introduction: Recent trial-level meta-analyses have established disease-free survival (DFS) as a valid surrogate for overall survival (OS) in human epidermal growth factor receptor 2-negative (HER2-) breast cancer (BC), irrespective of disease stage, and in early-stage hormone receptor-positive (HR+)/HER2- BC. To advance the understanding of the association between additional DFS endpoints and OS, this study assessed the patient-level correlations between DFS and OS, invasive DFS (IDFS) and OS, and distant DFS (DDFS) and OS in Medicare beneficiaries with early-stage HER2- BC, overall and in subgroups of patients with HR+/HER2- BC and triple-negative BC (TNBC).

Methods: Patients with stages I-III HER2- BC aged ≥ 66 years were identified from SEER-Medicare data (2010-2019).

Scoping Review: The Effects of Interrupted Onabotulinumtoxin A Treatment for Chronic Migraine Prevention During the COVID-19 Pandemic.

Objective: To systematically examine the literature on the clinical consequences of inadvertent delays in scheduled onabotulinumtoxin A (OTA) therapy for chronic migraine during the COVID-19 pandemic and assess recommendations when access to OTA is limited.

Background: The coronavirus (COVID-19) pandemic was unprecedented in its impact on the global medical community. Most healthcare institutions in the United States (US) and the world had begun significantly limiting elective procedures, undermining management of many debilitating chronic conditions.

Strategies of positron emission tomography (PET) tracer development for imaging of tau and α-synuclein in neurodegenerative disorders.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder, characterized by the presence of extracellular amyloid plaques consisting of β-amyloid peptides (Aβ) and intracellular neurofibrillary tangles (NFTs) composed of hyperphosphorylated tau (pTau) protein in the brain. Genetic and animal studies strongly indicate that Aβ, tau and neuroinflammation play important roles in the pathogenesis of AD. Several staging models showed that NFTs correlated well with the disease progression.

A foundation model for generalized brain MRI analysis.

Artificial intelligence (AI) applied to brain magnetic resonance imaging (MRI) has the potential to improve disease diagnosis and management but requires algorithms with generalizable knowledge that can perform well in a variety of clinical scenarios. The field has been constrained, thus far, by limited training data and task-specific models that do not generalize well across patient populations and medical tasks. Foundation models, by leveraging self-supervised learning, pretraining, and targeted adaptation, present a promising paradigm to overcome these limitations.

The Outcomes of Onco-Testis Sperm Extraction at the Time of Radical Orchiectomy.

Objective: To evaluate outcomes of onco-testis sperm extraction (TESE) and to define potential predictors of successful surgical sperm retrieval (SSR).

Methods: For this study, we examined all men (i) diagnosed with a testicular mass, (ii) who had azoospermia, and (iii) who underwent a radical orchiectomy and onco-TESE. Our institutional database of testicular cancer (TCA) patients was reviewed.

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.

Non-enhancing asymmetries on screening contrast-enhanced mammography: Is further diagnostic workup required?

Objectives: Asymmetries on screening contrast-enhanced mammography (CEM) often lead to patient recall. However, in diagnostic settings, negative CEM has effectively classified these as normal or benign, questioning the need for further workup of non-enhancing asymmetries (NEAs).

Material And Methods: A computational search of all screening CEM examinations performed between December-2012 and June-2021 was conducted to identify cases reporting NEAs.

Real-world experience with iron chelation therapy in transfusion-dependent thalassemia: impact of the oral chelators' era.

Iron overload is a common complication in patients with transfusion-dependent-thalassemia that can lead to end-organ damage. Management of iron overload has considerably evolved since the early 2000s with the approval of oral iron chelators and widespread use of MRI monitoring. We conducted a retrospective cohort study of 144 patients with transfusion-dependent-thalassemia treated at a single center in the US and followed since initiation of regular transfusion therapy.

Conserved roles of engrailed: patterning tissues and specifying cell types.

More than 40 years ago, studies of the Drosophila engrailed and Hox genes led to major discoveries that shaped the history of developmental biology. We learned that these genes define the state of determination of cells that populate particular spatially defined regions: the identity of segmental domains by Hox genes, and the identity of posterior developmental compartments by engrailed. Hence, the boundaries that delimit spatial domains depend on engrailed.

Non-RB1 germline cancer predisposing variants found in retinoblastoma patients.

Purpose: It is well known that individuals with hereditary retinoblastoma are at lifelong high risk for developing subsequent malignant neoplasms (SMN). However, the role that non- germline variants play in tumorigenesis and SMN risk has not yet been studied. The purpose of this study is to report the frequency and spectrum of non- germline cancer predisposing variants in individuals with retinoblastoma (RB).

Multi-institutional experience treating patients with cardiac devices on a 1.5 Tesla magnetic resonance-linear accelerator and workflow development for thoracic treatments.

Background And Purpose: Patients with cardiac implantable electronic devices (CIED patients) are often ineligible for online magnetic resonance-guided radiotherapy (MRgRT), most likely due to the absence of established guidelines. Existing radiotherapy (RT) and magnetic resonance imaging (MRI) guidelines offer an opportunity to construct MRgRT protocols, promoting equitable access. Our objective was to present such a workflow, share multi-institutional experiences treating CIED patients with MRgRT on a 1.

Efn1 and Efn2 are extracellular 5'-nucleotidases induced during the fission yeast response to phosphate starvation.

Unlabelled: The fission yeast regulon genes , , and -encoding a cell surface-associated acid phosphatase (Pho1), a plasma membrane inorganic phosphate transporter (Pho84), and a plasma membrane glycerophosphocholine transporter (Tgp1)-are strongly upregulated in response to acute phosphate starvation, as are the and genes that encode putative 5'-nucleotidase paralogs of the binuclear metallophosphoesterase enzyme superfamily. Via proteomic analysis of the medium harvested from phosphate-replete and phosphate-starved fission yeast, we define a starvation secretome that includes SPBPB2B2.06c (renamed Efn1, for xtracellular ive-prime ucleotidase), SPAC1039.

Contemporary trends in utilization of metastasectomy in the era of targeted and immunotherapies.

Background: Metastasectomy is a useful adjunct in the management of metastatic cancer. Widespread adoption of novel targeted and immunotherapies has improved the survival profiles of multiple malignancies, which has potentially altered the role of metastasectomy. This study aimed to characterize trends in metastasectomy across five primary cancers eligible for these therapies.

Assessing Attitudes and Perceptions of Unconscious Bias Experienced by Surgical Oncology Fellows.

Background: Racial and ethnic minorities remain underrepresented in the surgical workforce with well-documented barriers to diversity and inclusion, including financial support, lack of mentorship, and high attrition rates. Recent literature has documented race and sex discrimination in the training of surgical residents but little is known about the experience of discrimination at the surgical fellowship level. The goal of our study was to assess attitudes and perceptions of unconscious bias experienced during surgical oncology fellowship training at our institution.
