Promoting Community Awareness of Lung Cancer Screening Among Disparate Populations: Results of the cancer-Community Awareness Access Research and Education Project.

Background: Lung cancer is the no. 1 cause of cancer death in the United States. Racial/ethnic minority and medically underserved populations suffer higher mortality than whites.

Design of a Community-Based Lung Cancer Education, Prevention, and Screening Program.

Uptake of low-dose computed tomography (LDCT) for lung cancer screening is extremely low. Efforts to promote screening are warranted, especially among disparate groups such as racial/ethnic minorities and those of lower socioeconomic status. This article describes the design and implementation strategies of the ongoing cancer-Community Awareness Access Research and Education (c-CARE) program.

Demographic, psychosocial, and behavioral associations with cancer screening among a homeless population.

Background: Although cancer incidence and mortality is declining, cancer remains among the leading causes of death in the United States. Research shows that cancer morbidity and mortality can be reduced by early detection. Yet, both cancer risks and screening behavior remain understudied in the homeless population.

Pathway to Weight Maintenance: A-Qualitative Study with Church Health Advisors to Assess Weight Loss Maintenance Program Needs Among African-Americans.

Nearly 50% of African-American adults are obese. Obesity is a known contributor to chronic diseases such as type 2 diabetes mellitus (type 2 DM). Short-term Diabetes Prevention Programs (DPPs) achieve short-term weight loss success, but weight regain is common.

A Flex-Model for long-term assessment of community-residing older adults following disasters.

For the rapidly growing older adult population, disaster consequences are frequently life disruptive and even life threatening. By 2050, it is estimated that the global older adult population will reach 22 percent of the total. With declining health, this population poses a particular risk needing to be addressed in emergency preparedness and disaster recovery.

Seasonal influenza infection and live vaccine prime for a response to the 2009 pandemic H1N1 vaccine.

The robust immune response to a single dose of pandemic 2009 H1N1 vaccine suggests that a large segment of the population has been previously primed. We evaluated the effect of seasonal (s) H1N1 infection, s-trivalent inactivated vaccine (s-TIV), and trivalent s-live attenuated influenza vaccine (s-LAIV) before immunization with a pandemic live attenuated influenza vaccine (p-LAIV) in mice. We compared serum and mucosal antibody and pulmonary CD8 and CD4 responses and the virologic response to challenge with a wild-type 2009 pandemic H1N1 (p-H1N1) virus.

The PB2 subunit of the influenza virus RNA polymerase affects virulence by interacting with the mitochondrial antiviral signaling protein and inhibiting expression of beta interferon.

The PB2 subunit of the influenza virus RNA polymerase is a major virulence determinant of influenza viruses. However, the molecular mechanisms involved remain unknown. It was previously shown that the PB2 protein, in addition to its nuclear localization, also accumulates in the mitochondria.

Emergence of a group 3 coronavirus through recombination.

Analyses of turkey coronavirus (TCoV), an enteric disease virus that is highly similar to infectious bronchitis virus (IBV) an upper-respiratory tract disease virus in chickens, were conducted to determine the adaptive potential, and genetic changes associated with emergence of this group 3 coronavirus. Strains of TCoV that were pathogenic in poults and nonpathogenic in chickens did not adapt to cause disease in chickens. Comparative genomics revealed two recombination sites that replaced the spike gene in IBV with an unidentified sequence likely from another coronavirus, resulting in cross-species transmission and a pathogenicity shift.

Infectious bronchitis virus field vaccination coverage and persistence of Arkansas-type viruses in commercial broilers.

To determine the coverage of infectious bronchitis virus (IBV) vaccine field boost in commercial broilers, estimate the relative amount of vaccine virus in the trachea, and follow the clearance of the vaccine, we collected approximately 100 tracheal swabs at various times postvaccination from 10 different flocks and used real-time reverse transcriptase-PCR (RT-PCR) to detect the virus. This allowed us to detect vaccine virus in as few as 3% of the birds in a flock of 20,000 birds with a 95% confidence level. We found that the number of birds positive for IBV vaccine following vaccination in the field resembled a parabolic-shaped curve that peaked around 14 days postvaccination, or it resembled a sinusoidal-type wave with a frequency of about 2 wk.
