Preventive antibiotics
The risk of infectious transmission increases with the duration of tick attachment. It requires between 36 and 48 hours of attachment for the bacteria that causes Lyme to travel from within the tick into its saliva. If a deer tick that is sufficiently likely to be carrying Borrelia is found attached to a person and removed, and if the tick has been attached for 36 hours or is engorged, a single dose of doxycycline administered within the 72 hours after removal may reduce the risk of Lyme disease. It is not generally recommended for all people bitten, as development of infection is rare: about 50 bitten people would have to be treated this way to prevent one case of erythema migrans (i.e. the typical rash found in about 70–80% of people infected). Garden landscaping
Several landscaping practices may reduce risk of tick bites in residential yards. The lawn should be kept mowed, leaf litter and weeds removed and groundcover use avoided. Woodlands, shrubs, stone walls and wood piles should be separated from the lawn by a 3-ft-wide rock or woodchip barrier. Without vegetation on the barrier, ticks will tend not to cross it; acaricides may also be sprayed on it to kill ticks. A sun-exposed tick-safe zone at least 9 ft from the barrier should concentrate human activity on the yard, including any patios, playgrounds and gardening. Materials such as wood decking, concrete, bricks, gravel or woodchips may be used on the ground under patios and playgrounds so as to discourage ticks there.
Rats provided with an exercise wheel had a lower ratio of secondary bile acids to primary bile acids than sedentary rats in their feces. There is a positive association of exercise and physical activity with cancer prevention, tolerance to cancer-directed therapies (radiation and chemotherapy), reduction in recurrence, and improvement in survival.
