Examining the Effects of Different Coping Styles on Dependent Stress Generation

In this study, I prospectively examined the associations between different coping styles and stress. Stress can be classified as independent, which is stress that an individual has no control over, or dependent stress, which is stress that occurs because of the individuals’ actions. Coping is how individuals deal with that stress. With the role that coping plays in stress, I expected that it would relate to stress generation. I hypothesized that some forms of coping would prospectively predict the occurrence of less dependent stress but not independent stress. To test this hypothesis, I had college students (N=73) complete negative life events questionnaire (NLEQ) and the cope inventory at two time-points separated by approximately 10 weeks. Consistent with the idea that coping styles are related to stress generation, mental disengagement and behavioral disengagement were each cross-sectionally associated with dependent life stress, but not independent life stress. More importantly, as hypothesized, both active coping and acceptance coping prospectively predicted less dependent stress at the second timepoint, controlling for dependent stress at the first timepoint and coping at the second timepoint. No significant prospective associations were found between any coping styles and independent stress. This shows that specific styles of coping are prospectively linked to less dependent stress over time, which may have important implications for interventions aimed at decreasing the occurrence of stress-related disorders

Cardiovascular Efficacy and Safety of Bococizumab in High-Risk Patients

Bococizumab is a humanized monoclonal antibody that inhibits proprotein convertase subtilisin- kexin type 9 (PCSK9) and reduces levels of low-density lipoprotein (LDL) cholesterol. We sought to evaluate the efficacy of bococizumab in patients at high cardiovascular risk. METHODS In two parallel, multinational trials with different entry criteria for LDL cholesterol levels, we randomly assigned the 27,438 patients in the combined trials to receive bococizumab (at a dose of 150 mg) subcutaneously every 2 weeks or placebo. The primary end point was nonfatal myocardial infarction, nonfatal stroke, hospitalization for unstable angina requiring urgent revascularization, or cardiovascular death; 93% of the patients were receiving statin therapy at baseline. The trials were stopped early after the sponsor elected to discontinue the development of bococizumab owing in part to the development of high rates of antidrug antibodies, as seen in data from other studies in the program. The median follow-up was 10 months. RESULTS At 14 weeks, patients in the combined trials had a mean change from baseline in LDL cholesterol levels of -56.0% in the bococizumab group and +2.9% in the placebo group, for a between-group difference of -59.0 percentage points (P<0.001) and a median reduction from baseline of 64.2% (P<0.001). In the lower-risk, shorter-duration trial (in which the patients had a baseline LDL cholesterol level of ≥70 mg per deciliter [1.8 mmol per liter] and the median follow-up was 7 months), major cardiovascular events occurred in 173 patients each in the bococizumab group and the placebo group (hazard ratio, 0.99; 95% confidence interval [CI], 0.80 to 1.22; P = 0.94). In the higher-risk, longer-duration trial (in which the patients had a baseline LDL cholesterol level of ≥100 mg per deciliter [2.6 mmol per liter] and the median follow-up was 12 months), major cardiovascular events occurred in 179 and 224 patients, respectively (hazard ratio, 0.79; 95% CI, 0.65 to 0.97; P = 0.02). The hazard ratio for the primary end point in the combined trials was 0.88 (95% CI, 0.76 to 1.02; P = 0.08). Injection-site reactions were more common in the bococizumab group than in the placebo group (10.4% vs. 1.3%, P<0.001). CONCLUSIONS In two randomized trials comparing the PCSK9 inhibitor bococizumab with placebo, bococizumab had no benefit with respect to major adverse cardiovascular events in the trial involving lower-risk patients but did have a significant benefit in the trial involving higher-risk patients
