OBJECTIVE It has been hypothesized that people who typically report experiencing negative emotions are at greater risk for disease and those who typically report positive emotions are at less risk. We tested these hypotheses for host resistance to the common cold. METHODS Three hundred thirty-four healthy volunteers aged 18 to 54 years were assessed for(More)
OBJECTIVE Low childhood socioeconomic status (SES) is a risk factor for adult morbidity and mortality primarily attributable to cardiovascular disease. Here, we examine whether childhood SES is associated with adult host resistance to infectious illness, and whether the effect is limited to a critical period of low SES exposure, can be undone by changes in(More)
There is considerable evidence that social relationships can influence health, but only limited evidence on the health effects of the personality characteristics that are thought to mold people's social lives. We asked whether sociability predicts resistance to infectious disease and whether this relationship is attributable to the quality and quantity of(More)
OBJECTIVE We ask whether subjective socioeconomic status (SES) predicts who develops a common cold when exposed to a cold virus. DESIGN 193 healthy men and women ages 21-55 years were assessed for subjective (perceived rank) and objective SES, cognitive, affective and social dispositions, and health practices. Subsequently, they were exposed by nasal(More)
BACKGROUND Sleep quality is thought to be an important predictor of immunity and, in turn, susceptibility to the common cold. This article examines whether sleep duration and efficiency in the weeks preceding viral exposure are associated with cold susceptibility. METHODS A total of 153 healthy men and women (age range, 21-55 years) volunteered to(More)
OBJECTIVE In an earlier study, positive emotional style (PES) was associated with resistance to the common cold and a bias to underreport (relative to objective disease markers) symptom severity. This work did not control for social and cognitive factors closely associated with PES. We replicate the original study using a different virus and controls for(More)
This study determined the influence of serum neutralizing antibody titers on infection rate, symptom manifestations, and provoked signs and pathophysiologies in adults experimentally exposed to rhinovirus type 39 (RV-39). Antibody status was determined for 151 healthy volunteers who were then cloistered in a hotel for 6 days. At the end of the first(More)
This double-blind study determined the influence of serum neutralizing antibody titers on the rate of infection and magnitude of disease expression after experimental exposure of adult volunteers to rhinovirus strain Hanks (RV-H). A total of 133 healthy volunteers were tested for antibody status, cloistered for a 6-day period, and challenged with RV-H at(More)
OBJECTIVE To determine the role played by the tensor veli palatini and levator veli palatini muscles (mTVP and mLVP, respectively) in eustachian tube (ET) opening. DESIGN Prospective study. SETTING Research laboratories at a tertiary care hospital. PATIENTS Fifteen healthy adults with normal middle ears and documented ET openings. INTERVENTIONS(More)
OBJECTIVE Describes a method of dynamic video-endoscopy of the Eustachian tube (ET) orifice at the nasopharynx to quantitatively represent ET component movements during swallowing using a graphic function and analyze their importance to its opening mechanics. METHODS This was a pilot study of relational event capture using a polar coordinate system(More)
