The polygraphic findings from 11 future victims of sudden infant death syndrome (SIDS) are reported and compared with those of matched pairs of control infants. The recordings had been done to alleviate parental anxiety about sleep apnea. Four infants had siblings who were victims of SIDS. Two infants were studied 3.5 to 9.5 weeks before their deaths(More)
Clock genes are expressed in a self-perpetuating, circadian pattern in virtually every tissue including the human gastrointestinal tract. They coordinate cellular processes critical for tumor development, including cell proliferation, DNA damage response and apoptosis. Circadian rhythm disturbances have been associated with an increased risk for colon(More)
We studied the polygraphic sleep recordings of 30 infants who eventually died of sudden infant death syndrome (SIDS) and those of 60 matched control infants. All records were extracted from 20,750 sleep studies collected prospectively in 10 sleep laboratories. Of the 30 future SIDS victims, 5 were siblings of SIDS victims and 9 were studied after an(More)
In a Columbia, South Carolina-based case–control study, we developed a healthy lifestyle index from five modifiable lifestyle factors (smoking, alcohol intake, physical activity, diet, and body mass index), and examined the association between this lifestyle index and the risk of colorectal adenomatous polyps (adenoma). Participants were recruited from a(More)
STUDY OBJECTIVES A large proportion of individuals affected by sleep disorders are untreated and susceptible to accidents, injuries, long-term sequelae (e.g., risk of cardiovascular disease, cancer, psychiatric disorders), and increased mortality risk. Few studies have examined the scope and magnitude of sleep disorder diagnoses in the United States (US) or(More)
The following conclusions can be drawn from the study of 55 cases of I.T.P. of childhood. 1. I.T.P. evolving more than 6 months must always be considered as chronic, the disease having in these cases few chances of recovery without splenectomy. After 6 months evolution, it is probably possible to establish a prognosis and a therapeutic approach with little(More)
BACKGROUND Genetic variation within GSTM2-5 genes may interfere with detoxification of environmental compounds, thereby having a detrimental effect on lung function following exposures such as tobacco smoke. We aim to investigate the influence of variants and associated methylation in the GSTM gene cluster with changes in lung function growth during(More)
