A research team at the University of California, Riverside, has found that electronic cigarettes, often targeted to youth and pregnant women, produce a stress response in neural stem cells, which are critical cells in the brain.
Thirdhand smoke can damage epithelial cells in the respiratory system by stressing cells and causing them to fight for survival, a research team led by scientists at the University of California, Riverside, has found. The finding could assist physicians treating patients exposed to thirdhand smoke.
Guidelines that determine which smokers qualify for CT scans are excluding a significant number of African Americans who develop lung cancer, according to a study released today in JAMA Oncology.
An observational study suggests the US Preventive Services Task Force (USPSTF) lung cancer screening guidelines may be too conservative for African-American smokers and that some eligibility criteria changes could result in more screenings of African-American smokers at high risk for lung cancer. The study looked at new lung cancer cases in a predominantly low-income and African-American population group to assess their eligibility for lung cancer screening using the USPSTF criteria.
A simple set of decision-support tools combined with institutional buy-in can help increase the number of cancer patients who engage in treatment to help them quit tobacco, data from researchers in the Abramson Cancer Center at the University of Pennsylvania show.
A new study provides evidence to support a simple measurement for diagnosing clinically significant airflow obstruction, the key characteristic of chronic obstructive pulmonary disease (COPD), the fourth leading cause of death in the United States. The study found that a 70% ratio of two indicators of lung function proved as or more accurate than other thresholds for predicting COPD-related hospitalizations and deaths.
The adverse effect of maternal smoking during pregnancy is well established and associated with several negative neonatal outcomes (such as low birth weight and preterm birth). It is also evident in some studies that the semen quality of men exposed to prenatal maternal smoking is generally more impaired than that of unexposed men. However, there is little known about the effect of paternal smoking in the time leading up to and during pregnancy.
'Our findings suggest that certain types of stores -- tobacco shops, convenience stores and those with a lot of tobacco advertising -- are more likely to sell tobacco to a young person without checking his or her ID.'
Smoking increases both men's and women's risk of a major heart attack at all ages, but women smokers have a significantly higher increased risk compared to men, especially women under 50 years old, according to a study in the Journal of the American College of Cardiology. Despite the increased risk, smokers can reduce their risk to that of a never smoker in as little as a month after quitting.
Chronic diseases, such as stroke, ischemic heart disease, and lung cancer, now represent the leading causes of premature death in China, according to a new scientific study. The rise in non-communicable diseases reflects declines in maternal and child mortality over nearly three decades, largely the result of economic growth and increasing levels of education. In addition, China has instituted national programs targeting infectious diseases.
