What Are The Risks Of Lung Cancer Screenings? While early detection is the key to improving lung cancer survival chances, doctors may not be adequately discussing the risks of screening. Doctors, as per guidelines, are advised to openly communicate and discuss both the benefits and risks of lung cancer screening. But researchers at the University of North Carolina (UNC) found adequate explanations are not always provided to patients. The study titled "Evaluating
Shared Decision Making for Lung Cancer Screening" was published in JAMA Internal Medicine on Aug. 13. Among Americans, lung cancer is the leading cause of cancerrelated death with 154,050 deaths estimated to be occurring in 2018. Chances of survival improve if the cancer is detected in the early stages. The United States Preventive Services Task
Forcer ecommends lung cancer screening (LCS) for current smokers, those who have a history of smoking, and individuals aged 55 and 80 years old. But there are three possible risks linked to the screening process. False-positive results could occur, wrongly suggesting the presence of cancer despite it not being present. This can lead to unnecessary tests and surgeries, which may result in
complications. Secondly, overdiagnosis can take place when the screening identifies cases of cancer that would have never progressed into a problem for the patient. This can also result in unnecessary treatment And lastly, being exposed to repeated radiation from numerous screening tests has been linked to a low risk of causing cancer in patients who were otherwise healthy. ….Read More
Here's What Makes Seniors Feel and Act Younger A pair of new studies points towards two potential paths to the fountain of youth. When older adults feel more control of their lives and get more exercise, they feel younger -- and that improves their thinking, overall quality of life and longevity, the studies say. One study included 116 older adults (ages 60 to 90) and 106 younger adults (ages 18 to 36). For nine days, the participants kept track of how much control they felt they had each day and how old they felt. Among the older adults, there was a significant link between perceived level of control and how old they felt, according to the findings presented Thursday at the annual meeting of the
American Psychological Association, in San Francisco. "Shaping the daily environment in ways that allow older adults to exercise more control could be a helpful strategy for maintaining a youthful spirit and overall well-being," study presenter Jennifer Bellingtier said in an APA news release. She is a postdoctoral researcher at Friedrich Schiller University of Jena in Germany. "Some interventions could be formal, such as a regular meeting with a therapist to discuss ways to take control in situations where individuals can directly influence events, and
how to respond to situations that they cannot control," Bellingtier said. "Smartphone apps could be developed to deliver daily messages with suggestions for ways to enhance control that day and improve a person's overall feeling of control," she added. The second study, also presented at the APA meeting, found that increasing physical activity can help adults feel younger. It included 59 adults, ages 35 to 69, whose daily step counts were tracked. After five weeks, those with greater increases in their step counts felt younger. "Our results suggest that
promoting a more active lifestyle may result in a more youthful subjective age," study presenter Matthew Hughes said in the news release. Hughes is a postdoctoral scientist at the Adult Cognition Lab at the University of North Carolina, Greensboro. "As this was part of a pilot study, our sample size was small," he noted. "While the results suggest that walking may contribute to feeling younger, further research with a larger sample in a more controlled setting is needed to confirm." Research presented at medical meetings is considered preliminary until published in a peer-reviewed journal.
For Seniors, Getting Physical Protects the Heart If you're in your early 60s, becoming more active may reduce your risk of heart disease, researchers report. That's especially true for women, they added. "The 60 to 64 age range represents an important transition between work and retirement, when lifestyle behaviors tend to change. It may, therefore, be an opportunity to promote increased physical activity," said study author Ahmed Elhakeem.
"In addition, cardiovascular disease risk is higher in older adults. It's important to understand how activity might influence risk in this age group," Elhakeem said. "We found it's important to replace time spent sedentary with any intensity level of activity." Elhakeem is a senior research associate in epidemiology at the University of Bristol Medical School in England.
The study, published Aug. 8 in the Journal of the American Heart Association, included more than 1,600 British people in their early 60s who wore heart rate and movement sensors for five days. Their blood was analyzed for key signs of heart disease: inflammatory markers Creactive protein and interleukin 6 (IL-6); blood vessel function markers tissue-plasminogen
activator (t-PA) and E-Selectin (a molecule that plays an important part in inflammation); and cholesterol markers leptin and adiponectin. "We focused on these atherosclerosis biomarkers as they are less studied and have been shown to predict risk of cardiovascular events and death," Elhakeem said in a journal news release….Read More
