Investigators Explore Impact of Cigarette Smoking and Alcohol Consumption on Black Breast Cancer Survivors
Rutgers Cancer Institute of New Jersey Results Published in JAMA Network Open
Newswise — New Brunswick, N.J. – Investigators from Rutgers Cancer Institute of New Jersey, the state’s only National Cancer Institute-designated Comprehensive Cancer Center, together with RWJBarnabas Health, found that a higher risk of mortality in Black breast cancer survivors is associated with a history of cigarette smoking along with regular alcohol consumption at the time of diagnosis. The work, led by Nur Zeinomar, PhD, MPH, associate member of the Cancer Prevention and Control Program at Rutgers Cancer Institute, along with senior author Elisa V. Bandera, MD, PhD of Rutgers Cancer Institute, Rutgers School of Public Health and Rutgers Robert Wood Johnson Medical School,is published in JAMA Network Open (doi:10.1001/jamanetworkopen.2022.52371)
There is limited data about how lifestyle factors are associated with breast cancer prognosis in Black women, as the majority of evidence is based on studies in white breast cancer survivors.
Maintaining a healthy lifestyle, which includes limited alcohol consumption and avoiding smoking, has been associated with improved survival following a breast cancer diagnosis (Li Q et al. Breast Cancer. 2022 Nov;29(6):957-966.). In this population-based cohort study of 1,926 Black breast cancer survivors, researchers found that those who smoked at the time of breast cancer diagnosis had a 52 percent increased risk for death due to any cause, compared with those who never smoked. This association was most pronounced for women with greater ‘pack-years’ of smoking and who regularly consumed alcohol, suggesting that smoking at the time of diagnosis is associated with a higher risk of mortality among Black breast cancer survivors, report the authors.
“Our findings add to the evidence of the detrimental health impacts of smoking and underscore the need of tailored and targeted survivorship care for breast cancer survivors, particularly Black women and those with heavier levels of smoking,” notes Dr. Zeinomar, who is also an assistant professor of medicine at Rutgers Robert Wood Jonson Medical School. “According to the American Cancer Society, there is a 40 percent increased risk of death for Black women diagnosed with breast cancer compared to non-Hispanic white women, thus better understanding how these modifiable risk factors are associated with prognosis is important for clinical recommendations and management following a breast cancer diagnosis.”
The authors note limitations of the study include limited information on cigarette smoking and alcohol consumption after diagnosis, as well as data on other types of smoking including passive smoking and e-cigarette use. Additionally, both alcohol consumption and smoking could potentially be underreported as both exposures in the study were based on self-reporting. The investigators say future studies should examine the role of continued smoking after a cancer diagnosis as well as smoking cessation in breast cancer survivorship.

(Family Features) While most parents are good at keeping track of vaccines their kids need to stay healthy, many adults don’t realize there are immunizations important for keeping themselves heart-healthy, as well.
Adults, especially those with a history of heart disease or stroke, should take steps to stay up-to-date on preventive vaccines, particularly for the flu and COVID-19.
Influenza – While many experience just a few days of aches and chills, the flu can be deadly for some, including young children, the elderly and those with chronic conditions like heart disease, stroke and diabetes. There has also been research linking flu infection to cardiovascular disease (CVD). Getting a flu shot can not only prevent the flu, it may also reduce the risk of having a heart attack or stroke.
In fact, a study published in “Stroke” found that, among a group of people hospitalized for various reasons, those who experienced a flu-like illness within a month of their hospitalization were 38% more likely to have a stroke. Receiving the flu vaccine within a year prior to hospitalization lowered a person’s stroke risk to 11%.
“Getting an annual flu shot should be part of routine health care for all individuals, especially for people who are already living with chronic health conditions that put them at higher risk for heart attacks or strokes,” said Eduardo Sanchez, M.D., M.P.H., FAHA, American Heart Association chief medical officer for prevention. “The potentially serious complications of the flu are far greater for those with chronic diseases. This is true not just for older people but even those age 50 and younger who have a history of high blood pressure, heart disease or diabetes.”
COVID-19 – At the onset of the pandemic, the American Heart Association established the COVID-19 Cardiovascular Disease Registry, which found people with or at risk for CVD were more likely to become infected with and die from COVID-19. Additionally, the research found many people experience heart and vascular disease after getting COVID-19.
A study from the registry published in “Circulation: Arrhythmia and Electrophysiology” found new-onset atrial fibrillation in 1 in 20 patients hospitalized with COVID-19. Additionally, research also found people hospitalized with COVID-19 had a higher risk of stroke compared with people who had similar infectious conditions such as influenza or sepsis.
“We can’t stress enough the connections between COVID-19 and cardiovascular disease,” Sanchez said. “There is clear evidence that people who have heart and vascular disease and even those with CVD risk factors are more likely to get COVID and to have more severe complications from the virus.”
Other Immunizations – While flu and COVID-19 vaccines are of the utmost importance, there are a number of other immunizations that can help keep people heart-healthy.
- The pneumococcal vaccination protects against a common cause of severe pneumonia and is especially important for people 65 and older, and others with certain underlying medical conditions. This type of pneumonia can be deadly, especially for people already at high risk for health complications, including CVD. One shot is usually good for several years, although you may need a second one later depending on your age at your first shot.
- Shingles, a viral infection caused by the chickenpox virus, has been linked to an increased risk of stroke. More than 99% of people age 40 or older in the United States may carry the dormant chickenpox virus, also known as the varicella-zoster virus, and not even realize it.

Get chronic UTIs? Future treatments may add more bacteria to your bladder to beat back harmful microbes
Researchers developed a biomaterial releasing beneficial E. coli to combat urinary tract infections by outcompeting harmful bacteria, aiming to reduce antibiotic resistance and manage chronic UTIs effectively.
Sarguru Subash, Texas A&M University
Millions of people in the U.S. and around the world suffer from urinary tract infections every year. Some groups are especially prone to chronic UTIs, including women, older adults and some veterans.
These infections are typically treated with antibiotics, but overusing these drugs can make the microbes they target become resistant and reduce the medicines’ effectiveness.
To solve this problem of chronic UTIs and antibiotic resistance, we combined our expertise in microbiology and engineering to create a living material that houses a specific strain of beneficial E. coli. Our research shows that the “good” bacteria released from this biomaterial can compete with “bad” bacteria for nutrients and win, dramatically reducing the number of disease-causing microbes.
With further development, we believe this technique could help manage recurring UTIs that do not respond to antibiotics.
Bringing bacteria to the bladder
For the microbes living in people, nutrients are limited their presence varies between different parts of the body. Bacteria have to compete with other microbes and the host to acquire essential nutrients. By taking up available nutrients, beneficial bacteria can stop or slow the growth of harmful bacteria. When harmful bacteria are starved of important nutrients, they aren’t able to reach high enough numbers to cause disease.
Delivering beneficial bacteria to the bladder to prevent UTIs in challenging, though. For one, these helpful bacteria can naturally colonize only in people who are unable to fully empty their bladder, a condition called urinary retention. Even among these patients, how long these bacteria can colonize their bladders varies widely.
Current methods to deliver bacteria to the bladder are invasive and require repeated catheter insertion. Even when bacteria are successfully released into the bladder, urine will flush out these microbes because they cannot stick to the bladder wall.
Biomaterials to treat UTIs
Since beneficial bacteria cannot attach to and survive in the bladder for long, we developed a biomaterial that could slowly release bacteria in the bladder over time.
Our biomaterial is composed of living E. coli embedded in a matrix structure made of gel. It resembles a piece of jelly about 500 times smaller than a drop of water and can release bacteria for up to two weeks in the bladder. By delivering the bacteria via biomaterial, we overcome the need for the bacteria to attach to the bladder to persist in the organ.
We tested our biomaterial by placing it in human urine in petri dishes and exposing it to bacterial pathogens that cause UTIs. Our results showed that when mixed in a 50:50 ratio, the E. coli outcompeted the UTI-causing bacteria by increasing to around 85% of the total population. When we added more E. coli than UTI-causing bacteria, which is what we envision for future development and testing, the proportion of E. coli increased to over 99% of the population, essentially wiping out the UTI-causing bacteria. Moreoever, the biomaterial continued releasing E. coli for up to two weeks in human urine.
Our findings suggest that E.coli could stick around and survive in the bladder for extended periods of time and successfully decrease the growth of many types of bacteria that cause UTIs.
Improving biomaterials
Our findings show that E. coli can not only control harmful bacteria it’s closely related to but also a broad range of disease-causing bacteria in humans and animals. This means scientists might not need to identify different types of beneficial bacteria to control each pathogen – and there are many – that can cause a UTI.
Our team is currently evaluating how effectively our biomaterial can cure UTIs in mice. We are also working to identify the specific nutrients that beneficial and harmful bacteria compete over and what factors may help beneficial bacteria win. We could add these nutrients to our biomaterial to be released or withheld.
This research is still at an early stage, and clinical uses are not in development yet, so if it does reach patients it will be well in the future. We hope that our technology could be refined and applied to control other bacterial infections and some cancers caused by bacteria.
