Lung cancer screening prolongs lives in real-world study

Among US veterans, screening led to earlier lung cancer diagnoses and improved survival.

2024-06-10

(Press-News.org) Among US veterans diagnosed with lung cancer through the Veterans Health Administration healthcare system, those who underwent screening before diagnosis were more likely to be diagnosed with earlier stage disease and had a higher cure rate than those who had not been screened. The findings come from an observational study published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.

Lung cancer is the leading cause of cancer deaths worldwide, and most patients are diagnosed at an advanced stage. Early detection through screening could save lives, and current recommendations state that adults 50–80 years old with at least a 20-pack-year smoking history who currently smoke or have quit within the past 15 years should undergo annual imaging tests for lung cancer.

Such screening has been shown to be beneficial in clinical trials, but there are limited data on the real-world effectiveness of lung cancer screening. To investigate, researchers assessed the impact of screening among patients in the Veterans Health Administration healthcare system diagnosed with lung cancer from 2011–2018.

Among 57,919 individuals diagnosed with lung cancer, 2,167 (3.9%) underwent screening before diagnosis. Patients who underwent screening had higher rates of early (stage I) diagnoses compared with those who had no screening (52% versus 27%), lower rates of death from any cause (49.8% versus 72.1%), and death from cancer (41.0% versus 70.3%) over 5 years.

“It is incredible to witness how dedicated national efforts to increase lung cancer screening from the Lung Precision Oncology Program can lead to substantial improvements in lung cancer outcomes,” said co–corresponding author Michael Green, MD, PhD, of the University of Michigan and the Veterans Affairs Ann Arbor Healthcare System.

New study reveals links between social anxiety, depression and suicidal thoughts in adolescents

2024-06-10

Peer-reviewed – Observational study - People Adolescents who experience higher levels of social anxiety symptoms are more likely to report increased suicidal thoughts and other depressive symptoms two years later, according to new research. The University of East Anglia-led study sheds light on the pressing need for early interventions to address society anxiety in young people. Lead author Dr Kenny Chiu, Clinical Lecturer in Clinical Psychology at UEA’s Department of Clinical Psychology and Psychological Therapies, said: “Social Anxiety Disorder ...

Disturbed blood flow can damage the vessel wall in cases of aortic dilation

2024-06-10

Abnormal blood flow in the aorta is linked to inflammation and breakdown of the vessel wall in conditions where the aorta is dilated. This is shown in a study led by researchers at Linköping University. The findings can contribute to better diagnosis and open up new ways to assess the risk of serious and usually fatal complications, such as rupture of the aorta. All blood in the body passes through the heart about once a minute. With every heartbeat, blood from the heart is pumped up into the aorta. Dilation can occur in all parts ...

Psychosocial skills can stop relapse in people with eating disorders, says expert

2024-06-10

Health services should teach patients with eating disorders psychosocial skills to help more people recover and avoid relapse, according to an expert. Anorexia, bulimia and other eating issues affect millions of people, and eating disorder specialist Bethany Crowley warns that eating disorders are often misunderstood. She suggests a more integrated approach to treating people is needed, to focus on the whole person rather than just the disordered eating. Quieting negative thoughts, learning to cope with emotional triggers and practicing self-compassion are among nine key skills outlined by the therapist in a new book. An Integrative Approach to Treating Eating ...

The discovery of new turbulence transition in fusion plasmas

2024-06-10

Background Fusion energy is that released when two light nuclei combine to form a single heavier one (nuclear fusion reaction). Fusion energy-based power generation (fusion power plant) uses the energy generated when deuterium and tritium combine to form helium. A nuclear fusion reaction does not produce carbon dioxide. In addition, since it is possible to extract deuterium and tritium from the sea water, fusion energy is regarded as a sustainable energy source, and research into its practical application has been progressing rapidly ...

Glowing dye helps surgeons eradicate prostate cancer

2024-06-10

A glowing marker dye that sticks to prostate cancer cells could help surgeons to remove them in real-time, according to a study funded by Cancer Research UK. Cancer Research UK-funded scientists, based at the Nuffield Department of Surgical Sciences and the Department of Oncology, University of Oxford, Oxford University Hospitals and Oxford NIHR Biomedical Research Centre used a fluorescent dye attached to a special marker molecule to give medics a “second pair of eyes” during surgery for prostate cancer. Twenty-three men with prostate cancer were injected with the marker dye before undergoing prostate removal surgery. The marker dye found areas of cancerous tissue ...

Study: ALS patients treated by neurologists received better care

2024-06-08

ALS patients received better care if they were treated by a neurologist, a new study published in PLOS One has found. But researchers found that Black, older and socially disadvantaged ALS patients were less likely to see a neurologist, raising concerns about equity in treating the deadly disease. Patients who were treated by neurologists were more likely to receive interventions endorsed by the American Academy of Neurology. “This study highlights the importance of neurologist care for ALS patients and the need to overcome barriers and provide care that is more equitable for ALS patients,” ...

What makes roads safer? New UMD study uses AI to find out

2024-06-07

College Park, Md. – Most people use Google Street View to find their way. Dr. Quynh Nguyen, an epidemiologist and statistician at the University of Maryland School of Public Health, uses it to locate spots where your journey might abruptly end. In a study published June 6 in the British Medical Journal (BMJ) of Injury Prevention, Nguyen identifies uses AI tools to identify key environmental elements impacting car-related collisions as well as cyclist-related and pedestrian-related accidents. “Car crashes are the leading cause of death for young people ...

Accessibility issues in cancer care

2024-06-07

Researchers at the University of Michigan are finding that many patients may be encountering significant barriers to cancer care, even from their first phone call to a clinic. Patients attempting to access cancer care must go through several different levels of communication, both before their initial appointment with a physician and throughout their treatment. Making those first calls to learn more about available cancer care services or to schedule an appointment at a clinic is an important step toward beginning their treatment journey. “Racial and ethnic disparities have been observed in the outpatient visit rates for ...

Research details method to get efficient, environmentally friendly lithium

2024-06-07

As the electric vehicle market booms, the demand for lithium — the mineral required for lithium-ion batteries — has also soared. Global lithium production has more than tripled in the last decade. But current methods of extracting lithium from rock ores or brines are slow and come with high energy demands and environmental costs. They also require sources of lithium which are incredibly concentrated to begin with and are only found in a few countries. Now, researchers at the University of Chicago Pritzker School of Molecular Engineering (PME) have optimized a new method for extracting lithium from more dilute — and widespread — sources of the mineral, including seawater, ...

In new experiment, scientists record Earth’s radio waves from the moon

2024-06-07

On Feb. 22, a lunar lander named Odysseus touched down near the Moon’s South Pole and popped out four antennas to record radio waves around the surface—a moment University of Colorado Boulder astrophysicist Jack Burns hails as the “dawn of radio astronomy from the Moon.” It was a major achievement for the tenacious lander, which was built by the Houston-based company Intuitive Machines and had to overcome a series of technical difficulties to make it to the lunar surface. Burns is co-investigator on the radio experiment that flew aboard Odysseus called Radio wave Observations at the Lunar Surface ...
