Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Oral doxycycline versus intravenous ceftriaxone for European Lyme neuroborreliosis: a multicentre, non-inferiority, double-blind, randomised trial.
Use of intravenous penicillin and ceftriaxone to treat Lyme neuroborreliosis is well documented, although oral doxycycline could be a cost-effective alternative. We aimed to compare the efficacy of oral doxycycline with intravenous ceftriaxone for the treatment of Lyme neuroborreliosis. ⋯ Oral doxycycline is as efficient as intravenous ceftriaxone for the treatment of European adults with Lyme neuroborreliosis.

Randomized Controlled Trial Controlled Clinical Trial
Incident dementia and blood pressure lowering in the Hypertension in the Very Elderly Trial cognitive function assessment (HYVET-COG): a double-blind, placebo controlled trial.
Observational epidemiological studies have shown a positive association between hypertension and risk of incident dementia; however, the effects of antihypertensive therapy on cognitive function in controlled trials have been conflicting, and meta-analyses of the trials have not provided clear evidence of whether antihypertensive treatment reduces dementia incidence. The Hypertension in the Very Elderly trial (HYVET) was designed to assess the risks and benefits of treatment of hypertension in elderly patients and included an assessment of cognitive function. ⋯ Antihypertensive treatment in elderly patients does not statistically reduce incidence of dementia. This negative finding might have been due to the short follow-up, owing to the early termination of the trial, or the modest effect of treatment. Nevertheless, the HYVET findings, when included in a meta-analysis, might support antihypertensive treatment to reduce incident dementia.
