Flu season visitor restriction – age 16 or older (Restricción de visitantes durante la Temporada de Influenza (Flu) – Mayores de 16 años.)

Flu Season Visitor Restriction

Visitors temporarily restricted to age 16 or older

As a safety first organization, Christiana Care is implementing a temporary visitation age restriction starting Friday, Jan. 18. This temporary restriction protects patients, their loved ones and health care workers during this time of extremely high number of influenza cases and other respiratory illnesses circulating in our community.

The new restrictions limit visitors to patients in Christiana and Wilmington hospitals to persons age 16 or older. Children and teens younger than 16 years are most likely to get the flu and remain contagious longer than adults. This restriction does not apply to outpatient and ambulatory services. We began restricting visitors under the age of 16 years in our Neonatal Intensive Care Unit (NICU) and Women’s and Children’s areas on Jan. 18.

Thank you for your understanding and cooperation.

Restricción de visitantes durante la Temporada de Influenza (Flu)

Temporalmente solo se permiten los visitantes mayores de 16 años.

Como una organización que promueve la seguridad ante todo, Christiana Care está implementando una restricción temporal en la edad de visitantes a partir del viernes 18 de enero. Esta restricción temporal protege a los pacientes, a sus seres queridos y al personal de cuidados de salud durante esta época con un número extremadamente alto de casos de influenza y de otras enfermedades respiratorias que circulan en nuestra comunidad.

Las nuevas restricciones, en los hospitales Christiana y Wilmington, sólo permiten visitas a pacientes de personas mayores de 16 años. Los niños y adolescentes menores de 16 años son más propensos a contraer el flu y son contagiosos por más tiempo que los adultos. Esta restricción no aplica a las áreas de servicios ambulatorios. Comenzamos la restricción de visitas a menores de 16 años en nuestra Unidad de Cuidados Intensivos Neonatales (NICU) y en las áreas para Mujeres y Niños desde el 18 de enero.

Gracias por su comprensión y cooperación.

Senior Clinical Scientist

Jennifer Sims-Mourtada, Ph.D., is a senior research scientist and the Director of Translational Breast Cancer Research in the Center for Translational Cancer Research. Dr. Sims-Mourtada earned her doctorate in Immunology in 2004 from University of Texas Graduate School of Biomedical Sciences in Houston and completed her post-doctoral training in the Department of Experimental Radiation Oncology at the University of Texas M.D. Anderson Cancer Center in Houston. Prior to joining Christiana Care in 2011, she was the director of molecular research and development for RadioMedix Inc., a biotechnology company in Houston TX focused on the development of targeted radiotherapeutics for the detection and treatment of cancers. In addition to her research work, she is an Affiliated Associate Professor in the Departments of Medical Laboratory Sciences and Biological Sciences at the University of Delaware. She also sits on the Board of Directors for RadioMedix , Inc. and the Radioisotope Therapy of America (RITA) Foundation. She has published numerous papers on her research and has served as the principle investigator or co- investigator on numerous grants from the Department of Defense and National Institutes of Health. She serves as a reviewer for numerous journals and serves as the associate editor for Cancer Studies and Molecular Medicine. She has been a regular member of the Radiation Therapeutics and Biology (ONC-R) study section at the National Institutes of Health since 2008 and has also served as an ad-hoc reviewer for numerous other NIH panels. Additionally, she serves as a reviewer for the Congressionally Directed Medical Research Breast Cancer Program. Dr. Sims-Mourtada is a member of the American Association of Cancer Researchers, and the Society of Nuclear Medicine and Molecular Imaging.

Research interests

Women with triple negative breast cancer (TNBC) have worse outcomes than women with hormone receptor positive breast cancer. TNBC disproportionately affects younger women who are pre-menopausal, especially African American women. Treatment for TNBC is an unmet clinical need. Survival rates for women diagnosed with TNBC, who relapse within 5 years of treatment, are significantly lower than women with hormone receptor (ER/PR+) breast cancer. Understanding the mechanisms that drive growth of TNBC may lead to better treatment, and predictive biomarkers that may identify women at risk for early relapse.

Inflammation as a driver of triple negative breast cancer

Dr. Sims-Mourtada’s research seeks to provide insight as to what drives TNBC growth and resistance to current therapy. She proposes that the aggressive nature of TNBC is due to cells that are present in the microenvironment surrounding the tumor. Her team has found that TNBCs have high levels of inflammatory cells in and around the tumor. Inflammatory cells are present in TN breast lesions even before they become invasive, suggesting a role for these cells in tumor formation and progression. Data generated in the Sims-Mourtada lab indicate that inflammation is an early event in TNBC as opposed to other types of breast cancers. Her team is currently investigating the hypothesis that inflammatory cells found associated to pre-malignant breast lesions release factors that initiate a cascade of events that not only result in malignant transformation and growth of breast cancer, but may determine the type of breast cancer that develops. If that is the case, understanding how inflammation affects breast tissue can also aid prevention efforts and help to identify high risk populations. The lab is also investigating whether genetic variances in regions that increase chronic inflammation, or other chronic inflammatory conditions are associated to an increased risk of TNBC and if treatment with anti-inflammatory drugs, many of which are already FDA approved for the treatment of certain autoimmune conditions, may improve treatment outcomes for women with TNBC.

Chronic Inflammation as a regulator of stem cell plasticity

Dr. Sims-Mourtada’s team is also investigating how mechanisms which are normally involved in wound healing may promote resistance in breast cancer. Her lab has shown that a growth factor associated with inflammation and wound healing, known as hedgehog, can promote growth of a population of highly resistant cells after treatment with radiation and chemotherapy. These cells, known as breast cancer stem cells, resemble normal mammary stem cells, and have an unlimited life-span. They are not killed by standard treatments and can remain either locally within the breast tissue, or travel to distant sites and eventually lead to local or systemic recurrence. Her team is currently investigating how hedgehog interacts with other pathways involved in chronic inflammation and wound healing to promote de-differentiation of tumor cells into stem-like cancer cells with increased resistance and metastatic potential.
