 Exercise test predicts heart events in high risk asymptomatic men
Among men without heart disease but who have significant cardiac risk factors, a poor performance on an exercise treadmill test is associated with more than doubling of the risk for a heart attack or other coronary heart disease event, according to a report in Circulation: Journal of the American Heart Association.
A risk score of 9 percent or less is considered low risk, 10 percent to 19 percent is considered intermediate risk, while a score of more than 20 percent, meaning that the person has a one in five chance of an event in 10 years, is classified as high risk.
The study did not provide evidence to support exercise testing for asymptomatic women because the event rate in women was too low to suggest any significant correlations between the exercise results and future events, he said.

In this study the immunological responses in HAM/TSP patients and in HTLV-I asymptomatic carriers were compared using several immunological assays to identify immunological markers associated with progression from infection to disease.
A recent report [13] established a cohort of HTLV-I asymptomatic carries to study clinical events and documented an increased frequency of abnormalities, including a case of HAM/TSP.
Evaluation of immunological responses in patients with HAM/TSP and asymptomatic carries is important for the understanding of the pathogenesis of the HAM/TSP, and to identify early immunological markers associated with progression from infection to disease.

STANFORD, Calif. - Identifying and treating HIV-infected newborns is a race against the clock, according to a study from the Stanford University School of Medicine and Lucile Packard Children's Hospital.
When the researchers compared the outcomes in the first two groups, they found that any type of antiretroviral therapy delayed disease progression and enhanced survival.
"We've clearly shown that early treatment of asymptomatic infants-no matter what it is-makes a big difference in preventing or delaying the progression of the disease," said Maldonado.

Most patients with acute HCV infection are asymptomatic, but these acute infections evolve into chronic infections in the majority of patients.
To answer these questions, she conducted a randomized trial with 68 patients, mean age 32 years, with asymptomatic but proven acute HCV infection.
Initiation of therapy at 8 or 12 weeks leads to a higher sustained virologic response rate than at 20 weeks, particularly with treatment with interferon plus ribavirin, she added.

After 10 years, only 61.9% of those who presented with cirrhosis remained alive, compared with 94.0% of those without.
However, the researchers cautioned that the study is not a prospective, randomized trial -- something that may be difficult to perform in this relatively rare disease -- and argued that more cohort studies are needed before the wait-and-see approach is widely adopted.

 ADA.org: Science in the News: Incidence of Periodontal Disease in Patients with Reported Asymptomatic Third Molars
In the studies, the investigators evaluated signs of periodontal disease in reportedly asymptomatic third molars of young adults aged 20-35, including probing depth, radiographic examination, inflammatory mediators, or levels of pathogenic organisms.
Collectively, the study results indicate that there may be a higher incidence of periodontal disease associated with asymptomatic third molars in this age group than had been expected.
The authors extrapolate that the oral inflammation associated with periodontal disease of third molars may make young adults at increased risk for inflammation throughout the body, placing these patients at risk for numerous systemic diseases.
