Bone Marrow Myeloid-Lymphatic Progenitors Expand Tumor Lymphatic Vasculature Through Cell Fusion.

Unlabelled: Bone marrow (BM)-derived myeloid-lymphatic endothelial cell progenitors (M-LECPs) promote formation of tumor lymphatics that are responsible for metastasis to lymph nodes. The regenerative capacity of BM progenitors to other lineages is mediated through cell fusion, a process that delivers a pro-mitotic message directly to division-restricted cells. This suggested that M-LECPs might use a similar mechanism to induce division of lymphatic endothelial cells (LECs).

Characteristics, Treatment, and Survival of Male Breast Cancer: A 21-year Retrospective Analysis at a Community Academic Institute in Central Illinois.

Male breast cancer is an uncommon disease, representing a fraction of all breast cancer diagnoses. This study examines the characteristics, treatment, and outcomes of males with breast cancer at a community academic institute in central Illinois. We retrospectively reviewed the medical records of male patients with breast cancer treated between 2000 and 2021.

Study protocol for Adaptive ChemoTherapy for Ovarian cancer (ACTOv): a multicentre phase II randomised controlled trial to evaluate the efficacy of adaptive therapy (AT) with carboplatin, based on changes in CA125, in patients with relapsed platinum-sensitive high-grade serous or high-grade endometrioid ovarian cancer.

Introduction: Adaptive ChemoTherapy for Ovarian cancer (ACTOv) is a phase II, multicentre, randomised controlled trial, evaluating an adaptive therapy (AT) regimen with carboplatin in women with relapsed, platinum-sensitive high-grade serous or high-grade endometrioid cancer of the ovary, fallopian tube and peritoneum whose disease has progressed at least 6 months after day 1 of the last cycle of platinum-based chemotherapy. AT is a novel, evolutionarily informed approach to cancer treatment, which aims to exploit intratumoral competition between drug-sensitive and drug-resistant tumour subpopulations by modulating drug dose according to a patient's own response to the last round of treatment. ACTOv is the first clinical trial of AT in this disease setting.

Workplace violence in trauma centers: an American Trauma Society Position Statement.

In 1966, the National Academy of Sciences and National Research Council published 'Accidental Death and Disability: the Neglected Disease of Modern Society' which served as a national call to action to address the apparent public apathy towards the devastating and unnecessary toll that injury was taking on America. This white paper recommended the establishment of a National Trauma Association to drive public demand for injury prevention and mitigation. The American Association for the Surgery of Trauma heeding that call, founded the American Trauma Society (ATS) in 1968.

Loss of RAB25 Cooperates with Oncogenes in the Transformation of Human Mammary Epithelial Cells (HMECs) to Give Rise to Claudin-Low Tumors.

The loss of RAB25 expression-RAS superfamily of GTPase characteristic of numerous breast cancers-corresponds with H-RAS point mutations, particularly in triple-negative breast cancers (TNBC), a subtype associated with a poor prognosis. To address the poorly understood factors dictating the progression of TNBC tumors, we examine the cooperative effects that loss of RAB25 expression in human mammary epithelial cell (HMEC) lines with H-RAS mutations confers in tumorigenesis. HMECs were immortalized by transduction with LXSN CDK4 R24C, a mutant form of cyclin-dependent kinase, followed by transduction with hTERT, a catalytic subunit of the telomerase enzyme.

Teaching Physician Assistant Students to Care for People With Intellectual and Developmental Disabilities.

The purposes of this educational activity were to instill in students a greater empathy for patients with intellectual developmental disabilities, give students a better understanding of how to obtain a medical history for patients with communication limitations, teach students practical tips for obtaining a medical history and physical examination to increase competence in their future practice, and to build a relationship with a local organization that serves people with intellectual disabilities. An experiential learning activity was added to the curriculum of two courses for first-year PA students to accomplish these goals. The course instructors engaged in several planning meetings with a local residential facility for people with intellectual disabilities, including choosing patients that the students would assess.

Urinary bother, Urinalysis, and Two-Year Efficacy Follow-Up Results of Phase I Trial of Intravesical Bacillus Calmette-Guérin Combined with Intravenous Pembrolizumab in Recurrent or Persistent High-Grade Non-Muscle-Invasive Bladder Cancer after Previous Bacillus Calmette-Guérin Treatment.

Objective: To report urinary bother, urinalysis changes, disease-free survival (DFS), and overall survival (OS) over 2 years for subjects enrolled in a phase I dose-escalation trial (NCT02324582) of intravesical Bacillus Calmette-Guérin (BCG) in combination with systemic pembrolizumab for recurrent or persistent high-grade non-muscle invasive bladder cancer (HGNMIBC).

Methods: Eighteen patients consented to the study. Five were screen failures.

Quality of life following treatment with intra-arterial cisplatin with concurrent radiation and erlotinib for locally advanced head and neck cancer.

Objectives: Studies that focus on the feasibility of using erlotinib plus chemoradiation to treat locally advanced head and neck cancer have given hints of improved survival outcomes compared to chemoradiation alone. However, the influence of this treatment regimen on the quality of life of the patients has not been documented. We conducted a study of this triple combination and now have documented follow-up survival data as well as long-term quality of life (QoL) measures.

Impact of cytotoxic chemotherapy on aldo-keto reductase family 1 member B10 expression.

Objective: Aldo-keto reductase family 1 member B10 (AKR1B10) is a protein that is produced and secreted by a significant number of breast cancers. However, a potential confounder to the use of AKR1B10 as a tumor marker is its elevation in patients given cytotoxic chemotherapy. We therefore conducted a prospective study to analyze AKR1B10 levels in patients with breast cancer receiving neoadjuvant cytotoxic chemotherapy.

Addressing a Key Leadership Challenge: Workplace Violence.

Workplace violence is a growing concern among health care workers, especially staff working in emergency departments. Emergency department leaders have oversight accountability that includes mitigation of workplace violence risks and staff education related to workplace violence prevention. Challenges associated with workplace violence events include disruption of safe patient care, decreased staff job satisfaction, and increased turnover.

Leadership and Trauma-Informed Care: Working to Support Staff and Teams.

The concept of "trauma-informed care" as a paradigm in public health and human services has evolved over the past 30 years. Can trauma-informed practices be used as a leadership tool to help address staff/colleagues as they grapple with the concerns associated with a complex health care landscape? Trauma-informed care shifts the focus from "What's wrong with you?" to "What happened to you?" This powerful approach to addressing stress might help set the stage for caring and meaningful interactions among staff and colleagues before exchanges become fraught with blame and unproductive or toxic impacts on team-based relationships.

The Emergency Medical Services Sleep Health Study: A cluster-randomized trial.

Background: Greater than half of emergency medical services (EMS) clinician shift workers report poor sleep, fatigue, and inadequate recovery between shifts. We hypothesized that EMS clinicians randomized to receive tailored sleep health education would have improved sleep quality and less fatigue compared to wait-list controls after 3 months.

Methods: We used a cluster-randomized, 2-arm, wait-list control study design (clinicaltrials.

Identification of Somatic Mitochondrial DNA Mutations, Heteroplasmy, and Increased Levels of Catenanes in Tumor Specimens Obtained from Three Endometrial Cancer Patients.

Endometrial carcinoma (EC) is the most common type of gynecologic malignant epithelial tumor, with the death rate from this disease doubling over the past 20 years. Mitochondria provide cancer cells with necessary anabolic building blocks such as amino acids, lipids, and nucleotides, and EC samples have been shown to increase mitochondrial biogenesis. In cancer, mitochondrial DNA (mtDNA) heteroplasmy studies suggest that heteroplasmic variants encode predicted pathogenic proteins.

Consequences of Structural Urbanism: Urban-Rural Differences in Cancer Patients' Use and Perceived Importance of Supportive Care Services from a 2017-2018 Midwestern Survey.

Background: Structural inequities, in part, undergird urban-rural differences in cancer care. The current study aims to understand the potential consequences of structural inequities on rural and urban cancer patients' access to and perceived importance of supportive cancer care resources.

Methods: We used data collected from November 2017 to May 2018 from a larger cross-sectional needs assessment about patients' support needs, use of services, and perceptions at a Midwestern United States cancer center.

AKR1B10 as a Potential Novel Serum Biomarker for Breast Cancer: A Pilot Study.

Background: Aldo-keto reductase 1B10 (AKR1B10) is a secretory protein that is upregulated in breast cancer.

Objective: This case-controlled pilot study evaluated the serum level of AKR1B10 in healthy women and patients with a localized or metastatic breast cancer.

Methods: AKR1B10 levels were measured by ELISA and IHC in several patient cohorts.

Phase I trial of intravesical Bacillus Calmette-Guérin combined with intravenous pembrolizumab in recurrent or persistent high-grade non-muscle-invasive bladder cancer after previous Bacillus Calmette-Guérin treatment.

Objectives: We conducted the first phase I dose-escalation trial (NCT02324582) of intravesical Bacillus Calmette-Guérin (BCG) in combination with systemic pembrolizumab in patients with high-grade non-muscle-invasive bladder cancer (HGNMIBC) who had persistent or recurrent disease after prior intravesical therapy with BCG. The primary endpoint was the safety of this combination. The secondary endpoint was clinical activity at three months following BCG treatment.

Renal cell tumors convert natural killer cells to a proangiogenic phenotype.

Natural killer (NK) cells are classically associated with immune surveillance and destruction of tumor cells. Inconsistent with this function, NK cells are found in advanced human tumors including renal cell carcinoma (RCC). NK cells with non-classical phenotypes (CD56CD16; termed decidua NK (dNK) cells) accumulate at the maternal-fetal interface during embryo implantation.

Protocol for phase I study of pembrolizumab in combination with Bacillus Calmette-Guérin for patients with high-risk non-muscle invasive bladder cancer.

Introduction: The initial treatment for high-risk non-muscle invasive bladder cancer (NMIBC) is endoscopic resection of the tumour followed by BCG therapy. In those who develop recurrence, the standard treatment is radical cystectomy. Despite the advancement in surgical technique and postoperative care, the degree of morbidity associated with radical cystectomy remains high, therefore less invasive treatment modalities are desirable.

The most problematic symptoms of prion disease - an analysis of carer experiences.

Objectives: Prion diseases are rare dementias that most commonly occur sporadically, but can be inherited or acquired, and for which there is no cure. We sought to understand which prion disease symptoms are most problematic for carers, to inform the development of outcome measures.

Design: Self-completed questionnaire with follow-up of a subset of participants by structured interview.

Evaluating Adaptation of a Cancer Clinical Trial Decision Aid for Rural Cancer Patients: A Mixed-Methods Approach.

Rural-residing cancer patients often do not participate in clinical trials. Many patients misunderstand cancer clinical trials and their rights as participant. The purpose of this study is to modify a previously developed cancer clinical trials decision aid (DA), incorporating the unique needs of rural populations, and test its impact on knowledge and decision outcomes.

National Systematic Legal Review of State Policies on Emergency Medical Services Licensure Levels' Authority to Administer Opioid Antagonists.

Objective: Previous research conducted in November 2013 found there were a limited number of states and territories in the United States (US) that authorize emergency medical technicians (EMTs) and emergency medical responders (EMRs) to administer opioid antagonists. Given the continued increase in the number of opioid-related overdoses and deaths, many states have changed their policies to authorize EMTs and EMRs to administer opioid antagonists. The goal of this study is to provide an updated description of policy on EMS licensure levels' authority to administer opioid antagonists for all 50 US states, the District of Columbia (DC), and the Commonwealth of Puerto Rico (PR).

Characterization of immortalized human mammary epithelial cell line HMEC 2.6.

Primary human mammary epithelial cells have a limited life span which makes it difficult to study them in vitro for most purposes. To overcome this problem, we have developed a cell line that was immortalized using defined genetic elements, and we have characterized this immortalized non-tumorigenic human mammary epithelial cell line to establish it as a potential model system. human mammary epithelial cells were obtained from a healthy individual undergoing reduction mammoplasty at SIU School of Medicine.

Single nucleotide variant in Nucleoporin 107 may be predictive of sensitivity to chemotherapy in patients with ovarian cancer.

Background: Alterations in nuclear pore complex (NPC) genes have been previously associated with response to chemotherapy. Using agnostic exome sequencing, we envisioned that new alleles in NPC genes, predictive of sensitivity to platinum treatment, could be discovered.

Methods: Twenty-two platinum-sensitive and six platinum-resistant ovarian cancer patients were tested.

Immune Characterization of the Programmed Death Receptor Pathway in High Risk Prostate Cancer.

Background: Programmed cell death-1 (PD-1), a T-cell inhibitory receptor, and its ligand, PD-L1, have been reported to be expressed in many tumor types, and this expression has led to the development of many drugs targeting the PD-1 pathway. The objective of this study was to determine the expression of PD-1 and PD-L1 in high-grade prostate cancer tissues, and correlate the expression with disease and patient characteristics.

Materials And Methods: Immunohistochemistry for PD-1 (CD279), PD-L1 (B7-H1), and CD3 was performed and scored from 0 to 5 on prostatectomy/biopsy tissue samples taken from 25 men with high-grade prostate cancer.
