(Press-News.org) Smokers and people who recently quit are more likely to face complications after having an operation than non-smokers, a new study reveals.
Experts say there is an urgent need for focussed action to encourage people to stop smoking before undergoing elective surgery, after the pan-European research revealed that 19.5% of elective surgery patients are current smokers.
Backed by National Institute for Health and Care Research (NIHR) funding, researchers discovered higher smoking rates among younger patients (18-40 years: 26.8%) and male patients (22.1%). Healthy adults without long-term conditions also exhibited higher smoking rates (24.6%).
Publishing their findings in The Lancet Regional Health - Europe, researchers at the University of Birmingham, working with the STARSurg Collaborative, reveal that current smokers and recent ex-smokers (those quitting within six weeks to one year before surgery) face higher odds of postoperative complications compared to patients who had never smoked.
Lead author Dr. Sivesh Kamarajah, from the University of Birmingham, commented: "Our findings highlight the high prevalence of smoking among elective surgical patients, particularly among younger and healthier individuals. Since we know that these patients are more likely than non-smokers to experience postoperative complications requiring extra bed days, the potential cost to the NHS is huge.”
“This presents a unique opportunity for healthcare providers to put in place effective smoking cessation strategies, improving both short-term surgical outcomes and long-term health. Embedding strong programmes to help people quit smoking into elective surgical systems may lead to more efficient, preventive care across the entire health system.
Researchers analysed data from 16,327 patients across 442 hospitals in 29 European countries. The study was conducted as part of the CASCADE cohort study, involving a comprehensive analysis of smoking status and its impact on postoperative complications among patients undergoing elective abdominal surgery.
“We found high complication rates up to a year after quitting smoking, which is surprising and challenges current convention, added Dr Kamarajah. “Poor short-term outcomes amongst current smoker exposes the urgent need to strengthen smoking cessation pathways for planned elective surgical care, where waiting times may be up to three to six months before surgery.”
Tobacco smoking remains a leading risk factor globally, contributing to over 10% of all deaths and nearly 142 million years of life lost annually. Despite concerted public health measures, Europe retains the highest regional smoking prevalence, with 36% of men and 20% of women actively smoking.
Within healthcare, elective activities in secondary care, including planned surgery, represent a critical but underleveraged setting for preventive interventions such as smoking cessation. Existing guidelines recommend smoking cessation up to six weeks before surgery to reduce risk of complications; however, this guidance is largely based on studies conducted over a decade ago.

Study details role of protein that may play a key role in the development of schizophrenia
2025-04-17
Research published in the Journal of Neurochemistry has detailed the role of a protein, hnRNP A1, in the formation and stability of myelin, suggesting an important impact on neurodegenerative diseases and mental disorders such as multiple sclerosis and schizophrenia. The findings pave the way for new research and potential treatments.
Myelin is a fatty substance produced by oligodendrocytes (cells of the central nervous system) that forms a sheath, like a kind of “insulator.” It “protects” the extensions of neurons (axons) and increases the conduction speed of nerve impulses that carry information ...
Americans don’t think bird flu is a threat, study suggests
2025-04-17
New York, NY | April 17, 2025 - In an editorial in the American Journal of Public Health, a team led by researchers from the CUNY Graduate School of Public Health and Health Policy (CUNY SPH) say public ignorance and apathy towards bird flu (highly pathogenic avian influenza, or HPAI) could pose a serious obstacle to containing the virus and preventing a larger-scale public health crisis.
The authors, including CUNY SPH Assistant Professor Rachael Piltch-Loeb, Associate Professor Katarzyna Wyka, ...
New CDC report shows increase in autism in 2022 with notable shifts in race, ethnicity, and sex
2025-04-17
Researchers at the Johns Hopkins Bloomberg School of Public Health contributed to a new Centers for Disease Control and Prevention report examining autism among children who turned 4 and 8 years old in 2022. The CDC report, which includes data from 16 study sites across the U.S. including Maryland, found an overall prevalence of autism of 1 in 31 (3.2%) among 8-year-olds in 2022.
The Maryland study site, led by researchers at Bloomberg School’s Wendy Klag Center for Autism and Developmental Disabilities, found a prevalence of 1 in 38 (2.6%) ...
Modulating the brain’s immune system may curb damage in Alzheimer’s
2025-04-17
New research suggests that calming the brain’s immune cells might prevent or lessen the damaging inflammation seen in Alzheimer’s disease. The study points to the key role of the hormone and neurotransmitter norepinephrine, and this new understanding could pave the way for more focused treatments that start earlier and are tailored to the needs of each person.
“Norepinephrine is a major signaling factor in the brain and affects almost every cell type. In the context of neurodegenerative diseases such as Alzheimer’s disease, it ...

Millions could lose no-cost preventive services if SCOTUS upholds ruling
2025-04-17
A study by the Stanford Prevention Policy Modeling Lab (PPML) finds that almost 30% of privately insured individuals in the United States, or nearly 40 million people, use at least one of the free preventive health services guaranteed under the Affordable Care Act (ACA).
But those services are now under threat by an ongoing legal challenge.
On April 21, the Supreme Court will hear arguments in Kennedy v. Braidwood Management Inc. to decide whether to uphold the ruling from a Texas district court that the ACA preventive services mandate was unconstitutional.
The ACA requires that private insurers cover specific preventive services at no cost to ...
Research spotlight: Deer hunting season linked to rise in non-hunting firearm incidents
2025-04-17
How would you summarize your study for a lay audience?
We wanted to study any changes in firearm incidents—both hunting-related and non-hunting-related—brought on by deer hunting season. We looked at four years’ worth of data across 10 states where hunting is popular. We found an unsurprising increase in hunting-related firearm incidents, but we also saw increases in the rates of non-hunting related firearm incidents, including those categorized as suicide, involving alcohol or other substances, domestic violence, home invasion or robberies, and defensive use; meanwhile, there were no changes in incidents involving police officers or children.

Rice scientists uncover quantum surprise: Matter mediates ultrastrong coupling between light particles
2025-04-17
HOUSTON – (April 17, 2025) – A team of Rice University researchers has developed a new way to control light interactions using a specially engineered structure called a 3D photonic-crystal cavity. Their work, published in the journal Nature Communications, lays the foundation for technologies that could enable transformative advancements in quantum computing, quantum communication and other quantum-based technologies.
“Imagine standing in a room surrounded by mirrors,” said Fuyang Tay, an alumnus of Rice’s Applied Physics Graduate Program and first author of the study. “If you shine a flashlight inside, the light will bounce back and ...
