Question: Is cigarette smoking associated with a reduction in the risk of incident gout : results from the Framingham Heart Study original cohort?
Answer: Cigarette smoking is associated with lower incidence of gout and this is not explained by differences in the prevalence of risk factors. The mechanistic underpinnings of this epidemiological finding merits further study.
yes

Question: Does a shoe insole delivering subsensory vibratory noise improve balance and gait in healthy elderly people?
Answer: This study provides proof of concept that the application of the principle of stochastic resonance to the foot sole sensory system using a new low-voltage piezoelectric technology can improve measures of balance and gait that are associated with falls. Effective vibratory noise amplitudes range from 70% to 85% of the sensory threshold and can be set once daily.
yes

Question: Is elective groin irradiation indicated for patients with adenocarcinoma of the rectum extending to the anal canal?
Answer: Inguinal nodal failure in rectal cancer patients with ACI treated with neoadjuvant or adjuvant chemoradiation is not high enough to justify routine elective groin irradiation.
