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.
New research reveals that overheating and thermal stress can contribute to the development of Sudden Infant Death Syndrome (SIDS). 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.
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.

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.
