Cystine kidney stones frequently recur because inadequate prevention exists. We recruited documented recurrent cystine kidney stone formers (6 men, 4 women, 44 ± 17 years) into a 2-phased study to assess safety and effectiveness of Cystone®, a herbal treatment used to prevent and facilitate passage of cystine kidney stones. The first phase was a randomized double-blinded 12 weeks crossover study assessing the effect of Cystone® versus placebo (2 tablets BID) on urinary chemistries.

Methods: We studied characteristics that might be predictive of blood pressure (BP) response in 203 African-American and 236 non-Hispanic white subjects with essential hypertension treated with candesartan, 32 mg/day for 6 weeks, after a drug-free washout period of at least 4 weeks (baseline). Measurements at enrollment, baseline, and at the end of the treatment were incorporated into linear regression models to quantify their additive contributions to predicting response.
Cerebral white matter hyperintensities on brain MRI (leukoaraiosis) are associated with increased risk of stroke and dementia. To assess the relationships of blood pressure level and circadian pattern with leukoaraiosis, we obtained 24-hour ambulatory blood pressure recordings and brain magnetic resonance images in 343 white and 267 black adults who were members of sibships that had >or=2 siblings with essential hypertension. In multiple linear regression models, factors associated with greater leukoaraiosis in both racial groups included age (P
Objective: To assess whether a physician-nurse team model could improve long-term hypertension control rates by active intervention and modification of antihypertensive drug regimens based on home blood pressure (BP) measurements.
Patients And Methods: This study consisted of patients referred to a hypertension specialty clinic between July 1999 and June 2002 for the evaluation and management of uncontrolled hypertension. Patients were evaluated initially by a physician.
