The study, led by Dr. Shabih Hasan, found that increased ambient temperatures, smoking during pregnancy, and exposure to cigarette smoke can all increase the risk of SIDS.
A new study links smoking during pregnancy to Sudden Infant Death Syndrome (SIDS) with the strongest causal link yet. The research found that prenatal cigarette smoke exposure can increase the likelihood of gasp-like respiration and prolong breathing time after hypoxia, placing infants at higher risk for SIDS.
Exposure to secondhand tobacco smoke increases the risk of severe infectious illnesses and hospital admissions in young children. Children born prematurely or with low birth weight are particularly vulnerable to these risks.
A new report from Research Australia reveals a strong link between childhood ear infections and exposure to passive tobacco smoke. The study found that Aboriginal children were more likely to develop middle ear infections and experience hearing loss due to early exposure to environmental tobacco smoke.
Researchers found that girls and children with exposure to secondhand tobacco smoke respond better to montelukast. The medication effectively controls asthma symptoms in these patients by reducing leukotriene levels.
A new study from researchers at the University of Alabama at Birmingham found that carbon monoxide in air pollution and tobacco smoke triggers tuberculosis infection to shift into a dormant state. This dormant state is difficult to detect and treat, contributing to the spread of TB and its high mortality rate.
Researchers found that a portable anteroom HEPA filtration unit can effectively remove airborne microorganisms, including M. tuberculosis, from operating rooms. The study suggests that this unit can help prevent secondary transmission of airborne pathogens and improve patient and healthcare personnel safety.

Additionally, research suggests that to stabilize global temperatures, future greenhouse gas emissions must be eliminated, committing the climate system to warming on centennial timescales.
Researchers used a NYC high-rise as a fire laboratory to study wind-driven flame, smoke, and gas spread through corridors and stairways. Positive pressure ventilation fans and prototype devices helped control deadly heat and smoke from wind-driven fires.
Researchers found that toddlers aged 2-5 years absorbed more nicotine from secondhand smoke than adolescents, leading to increased markers of inflammation and vascular injury. This exposure resulted in damage to the endothelium, the inner lining of vessel walls, increasing the risk of heart disease.
A global study found that 82 percent of parents who smoked reported smoking around their children, exposing them to high levels of secondhand smoke. Hair nicotine levels were detected in 78 percent of children living with a smoker and 59 percent without, highlighting the need for improved public awareness.
A toxic pollutant found in cigarette smoke, benzo(a)pyrene (BaP), has been shown to slow bone healing by interfering with the process of stem cells becoming cartilage cells. This delay can lead to chronic pain and disability.
Researchers identify hydrogen peroxide in cigarette smoke as a primary cause of lung cancer development. The study may lead to the development of 'safer' cigarettes and new treatments for lung cancer.
