Although obesity is a risk factor for mortality, it is unclear whether waist circumference (WC) is a better predictor of mortality than BMI in a clinical setting of patients at high risk for coronary artery disease (CAD). Thus, we compared the association between WC and BMI with all‐cause mortality in relation to traditional CAD risk factors in a high‐risk cohort. Study population included 5,453 consecutive new patients seen between 1996 and 2005 for management of CAD risk factors in a preventive cardiology clinic. Mortality was determined from the Social Security Death Index. There were 359 deaths over a median follow‐up of 5.2 years. Mortality was greater in high (>102 cm in men and >88 cm in women) vs. normal WC in both genders (P < 0.01). The unadjusted Cox proportional hazard ratio (HR) for continuous WC (per cm) was 1.02 (P < 0.001) in both genders and remained significant after adjustment for CAD risk factors (HR = 1.01 in men, HR = 1.03 in women, both P < 0.05). BMI did not associate statistically with mortality. WC associated with diabetes mellitus (DM) and CAD prevalence (P < 0.001). BMI associated only with DM (P < 0.001) and this association disappeared when WC was added to the model. We conclude that WC is an independent predictor of all‐cause mortality in a preventive cardiology population. These data affirm the clinical importance of WC measurements for mortality, DM, and CAD risk prediction and suggest that obesity‐specific interventions targeting WC in addition to traditional risk factor management may favorably impact these outcomes.

DM group had highest mortality and CVD prevalence vs. MS and non-DM/non-MS groups respectively (all p < or = 0.001). Patients with MS criteria had increased CVD prevalence and 1.5-fold increased mortality vs. non-DM/non-MS group (all p < 0.02). In NCEP MS criteria, only fasting glucose significantly predicted mortality in MS group (p = 0.05). MS criteria predicted CVD prevalence in a parallel manner to Framingham risk score assessment. In a cohort of patients at high risk for CVD whose risk factors are being treated, presence of diabetes in addition to plasma glucose within NCEP MS criteria strongly predicts all-cause mortality.

Self-monitoring of blood glucose is a critical element in diabetes management. Providers must determine if and when patients are to perform glucose self-monitoring, set blood glucose targets, and help patients to interpret the results. Patients have a variety of continually evolving meters, supplies, and technology from which to choose. Making sense of these expectations and options is perhaps the greatest challenge for providers and patients. Working together, healthcare providers and certified diabetes educators can ensure that people with diabetes get the most out of self-monitoring of blood glucose.

Prolactin has been proposed as a potent coactivator of platelet aggregation, possibly contributing to thromboembolic events. The objective of the study was to evaluate the relationship between prolactinoma and deep vein thrombosis (DVT), pulmonary embolism (PE), and cerebrovascular accident (CVA). Subjects were identified from a prospectively maintained pituitary database at the Cleveland Clinic. We retrospectively reviewed the charts of 544 subjects: 347 patients with prolactinomas (prolactinoma group) and 197 patients with nonfunctional pituitary adenomas (control group). Main outcome measures were DVT, PE and CVA. We found that 19 (5.5%) patients in the prolactinoma group and five (2.5%) patients in the control group had documented DVT, PE, or CVA, but this difference was not significant (p = 0.109). However, the mean initial prolactin level was higher at the time of diagnosis among prolactinoma patients than among controls (815.23 ng/ml vs. 15.90 ng/ml; p < 0.001). Among prolactinoma patients, 15 (5.5%) of 275 patients who underwent medical treatment (with cabergoline, bromocriptine, pergolide and/or other drug) and 4 (5.6%) of 72 patients who underwent transsphenoidal surgery had documented DVT, PE, or CVA, which suggests that dopaminergic therapy did not influence the risk of thromboembolic events. Hyperprolactinemia per se does not appear to predispose to a hypercoagulable state.

Bisphosphonates are widely used as first-line therapy to slow bone loss and decrease fracture risk in postmenopausal women with osteoporosis. Nonadherence to oral bisphosphonates diminishes the benefit of reduced bone loss and fracture risk of these medications. Strategies to enhance osteoporosis monitoring and adherence to therapy are crucial to improve outcomes. Dual-energy x-ray absorptiometry (DXA) is the gold standard for monitoring bone mineral density but is slow to detect change after initiation of oral bisphosphonate therapy. Bone turnover markers (BTMs) are by-products released during bone remodeling and are measurable in blood and urine. We review how the rapid change in BTMs can be a useful short-term tool to monitor the effectiveness of oral bisphosphonate therapy, which may ultimately improve adherence to therapy and outcomes. KEY POINTSOral bisphosphonates slow bone loss and reduce the risk of fracture in postmenopausal women with osteoporosis.Nonadherence to bisphosphonate therapy diminishes the benefits of these medications.BTMs are a simple, low-risk, and convenient way to monitor effectiveness and adherence to oral bisphosphonate therapy in addition to DXA.Bisphosophonates induce a rapid dose-dependent decrease in bone resorption markers, making them an excellent tool to ascertain adherence to and efficacy of oral antiresorptive therapy.
