Selective reporting of outcomes within published studies based on the nature or direction of their results has been widely suspected, but direct evidence of such bias is currently limited to case reports. ⋯ The reporting of trial outcomes is not only frequently incomplete but also biased and inconsistent with protocols. Published articles, as well as reviews that incorporate them, may therefore be unreliable and overestimate the benefits of an intervention. To ensure transparency, planned trials should be registered and protocols should be made publicly available prior to trial completion.

Heart failure accounts for more hospitalizations among Medicare beneficiaries than any other condition. Its symptoms, including shortness of breath, fatigue, and edema, can be frightening and diminish quality of life. Although treatment advances have allowed patients to live longer with a better quality of life, heart failure remains a leading cause of death in the United States. ⋯ Given the availability of effective treatments, the prevalence of distressing symptoms, and a persistent high risk of death that may occur suddenly, physicians must simultaneously treat the underlying condition while helping patients plan for future needs and complete advance directives. Using the case of Mr R, a 74-year-old man with heart failure, we illustrate ways that physicians can address these issues to improve the care of patients with heart failure, including symptom management and discussing advance directives, prognosis, and hospice care. By combining optimal medical management with palliative care, physicians can best care for heart failure patients and their families.

Because of methodological limitations, the results of the few prospective studies assessing long-term cognitive effects of prenatal cocaine exposure are inconsistent. ⋯ Prenatal cocaine exposure was not associated with lower full-scale, verbal, or performance IQ scores but was associated with an increased risk for specific cognitive impairments and lower likelihood of IQ above the normative mean at 4 years. A better home environment was associated with IQ scores for cocaine-exposed children that are similar to scores in nonexposed children.

Randomized Controlled Trial Multicenter Study Clinical Trial
Terminal complement blockade with pexelizumab during coronary artery bypass graft surgery requiring cardiopulmonary bypass: a randomized trial.
Inflammation and ischemia-reperfusion injury during coronary artery bypass graft (CABG) surgery requiring cardiopulmonary bypass are associated with postoperative myocardial infarction (MI) and mortality. ⋯ Compared with placebo, pexelizumab was not associated with a significant reduction in the risk of the composite end point of death or MI in 2746 patients who had undergone CABG surgery only but was associated with a statistically significant risk reduction 30 days after the procedure among all 3099 patients undergoing CABG with or without valve surgery.
