Chances of quitting smoking improve with integrated care, including medication and counseling

For smokers undergoing lung cancer screening, medication coupled with intensive counselling was the optimal smoking cessation intervention, study finds

Chances of quitting smoking improve with integrated care, including medication and counseling
2025-01-13
(Press-News.org) HOUSTON ― Smokers undergoing lung cancer screening may have the best chance of quitting if they receive integrated care, which includes medication and comprehensive counseling with tobacco treatment specialists, according to researchers at The University of Texas MD Anderson Cancer Center.  

The study results, published today in JAMA Internal Medicine, demonstrated that integrated care outperformed other cessation methods with a nearly two-fold improvement in the odds of quitting. In this randomized clinical trial of 630 current smokers who were eligible for lung cancer screening, over 30% of those who received integrated care were still abstaining from smoking after six months.  

"For those who smoke, lung cancer screening presents a critical opportunity for us to support them in quitting," said principal investigator Paul Cinciripini, Ph.D., chair of Behavioral Science and executive director of the Tobacco Research and Treatment Program at MD Anderson. "Our study demonstrates that providing access to effective medications and trained tobacco cessation specialists offers the greatest chance at successfully quitting and, hopefully, avoiding the potential of lung cancer.”  

Lung cancer is the leading cause of cancer mortality in the U.S. and the second most diagnosed cancer, accounting for one in five cancer-related deaths. Tobacco use is responsible for 85% of lung cancer cases and contributes to nearly 30% of all cancer-related deaths. Each year, an estimated 480,000 Americans die from tobacco-related illnesses. 

The average smoker makes several attempts to quit before successfully beating the addiction. MD Anderson’s Tobacco Research and Treatment Program tackles the barriers to cessation at an individual and population level, and its scientists conduct research designed to change clinical practice by addressing knowledge gaps among health care providers treating tobacco addiction.  

In this study, participants were recruited from Houston between July 2017-2021. They were at least 50 years old and smoked a median of 20 cigarettes per day. The participants were randomized into three groups of 210, receiving the following interventions: a quitline referral and nicotine replacement therapy (NRT) (QL); a quitline referral plus NRT or medication prescribed by a lung cancer screening clinician (QL+); or integrated care (IC), which included NRT or prescription pharmacotherapy and counseling, provided by a team of tobacco treatment specialists and physicians.  

At the three-month mark, IC had the highest quit rate, 37.1%, compared to 27.1% in the QL+ and 25.2% in the QL cohorts. At the six-month mark, IC maintained the highest quit rate, 32.4%, compared to 27.6% for the QL+ group and 20.5% for the QL group.  

"Facilities equipped to provide dedicated and integrated care should prioritize doing so to offer patients the best opportunity for smoking cessation and improved health outcomes," Cinciripini said. "Given our results, it is conceivable that this approach could also be highly effective outside a screening environment, such as post-traumatic stress clinics and among patients with cancer, cardiovascular disease or diabetes." 

Limitations of this study include that the population was predominately white, and that the entire sample lacked CO (expired carbon monoxide) abstinence verification due to covid restrictions after the study had begun, although overall results between sub-samples with and without verification were similar.  

This research was supported by the National Cancer Institute (R01CA207078, P30CA016672), the MD Anderson Lung Cancer Moon Shot™, the State of Texas Permanent Health Funds, and the Margaret and Ben Love Chair in Clinical Cancer Care in Honor of Dr. Charles A. LeMaistre. Varenicline was supplied by Pfizer Pharmaceuticals, and quitline services were provided by RVO Health.

From microplastics to macro-impact: KTU expert explains plastic recycling challenges
2025-01-13
“Microplastic particles are currently found almost everywhere – in water, food, fish, and even breast milk,” says Artūras Torkelis, a PhD student at Kaunas University of Technology (KTU). He emphasises that proper waste management is essential for reducing these risks. The use of plastic in Europe has skyrocketed over the past decade. Recent statistics reveal that in 2021, each person in the European Union (EU) generated an average of 36 kg of plastic packaging waste. Of the more than 16 million tonnes of plastic packaging generated that year, only 6.5 million tonnes were recycled. Plastic recycling remains a serious problem. ...

How does the brain encode pain? Scientists uncover neuronal mechanisms of pain intensity encoding

How does the brain encode pain? Scientists uncover neuronal mechanisms of pain intensity encoding
2025-01-13
A research team led by Prof. HU Li at the Institute of Psychology of the Chinese Academy of Sciences, has revealed that parvalbumin (PV) interneurons in the primary somatosensory cortex (S1) preferentially encode pain intensity and drive nociceptive-evoked gamma oscillations (GBOs). Published online in Neuron on January 13, the study fills a longstanding gap in understanding the origins of nociceptive-evoked GBOs and their selective relationship with pain processing across different species. The findings suggest the potential for using these oscillations as a promising target for therapeutic interventions. Pain is a ...

Study finds opioid pain medications very infrequently prescribed to NFL players

2025-01-13
INDIANAPOLIS – Due to the physical contact nature of their occupation, the elite athletes of the National Football League (NFL) often experience pain. However, an analysis of 2021 and 2022 data from the National Football League Prescription Drug Monitoring Program shows that team members in those two years were even less likely than both the general U.S. population and males of similar age living in the U.S., to have a prescription for an opioid pain medication. The study found that less than 3 percent of pain medications prescribed to the athletes who played in one or both of the two seasons were for opioids. Slightly more than 86 percent of the ...

Wrong place, wrong time: Why Zika virus hijacks a protein needed for brain growth

2025-01-13
The mosquito-borne Zika virus is known for causing microcephaly, a birth defect in which abnormal brain development results in a smaller-than-expected head. A new study published Jan. 13 in mBio shows that the Zika virus hijacks a host protein called ANKLE2, which happens to be important for brain development, to assist its own reproduction. Because Zika, unlike most related viruses, can cross the placenta, this can have disastrous consequences in pregnancy.  “It’s a case of Zika being in the wrong place at the wrong time,” said Priya Shah, associate professor in the departments of Microbiology and Molecular ...
