Infectious diseases may rival cancer, heart disease, and chronic lung disease as sources of morbidity and mortality from smoking. We reviewed mechanisms by which smoking increases the risk of infection and the epidemiology of smoking-related infection, and delineated implications of this increased risk of infection among cigarette smokers. ⋯ The clinical implications of our findings include emphasizing the importance of smoking cessation as part of the therapeutic plan for people with serious infectious diseases or periodontitis, and individuals who have positive results of tuberculin skin tests. Controlling exposure to secondhand cigarette smoke in children is important to reduce the risks of meningococcal disease and otitis media, and in adults to reduce the risk of influenza and meningococcal disease. Other recommendations include pneumococcal and influenza vaccine in all smokers and acyclovir treatment for varicella in smokers.

The association between menopausal hormone therapy (HT) and risk of ovarian cancer is as yet equivocal, and the effect of estrogen and estrogen-progestogen therapy, specifically the effect of the cumulative hormone intake, is unclear. ⋯ Oral HT is associated with risk of ovarian cancer in women who have not undergone hysterectomy. Our results imply that the risk increases with cumulative oral estrogen intake but not with duration of HT, indicating that the increased ovarian cancer risk associated with oral HT may be diminished substantially by minimizing the daily dose of estrogen from oral HT.

Meta Analysis Comparative Study
A meta-analysis comparing the effect of thiazolidinediones on cardiovascular risk factors.
In patients with type 2 diabetes mellitus, all therapeutic options should be evaluated for their effect on cardiovascular risk factors, in addition to glycemic control. We conducted a meta-analysis of randomized controlled trials of pioglitazone hydrochloride and rosiglitazone maleate in patients with type 2 diabetes to evaluate their effect on glycemic control, lipids, blood pressure, and weight. ⋯ Thiazolidinediones have similar effects on glycemic control and body weight. Pioglitazone produced a more favorable lipid profile. Head-to-head comparative trials as well as longer-term cardiovascular outcome studies are needed to determine whether there are differences in efficacy between the 2 thiazolidinediones.

Multicenter Study
Talking with terminally ill patients and their caregivers about death, dying, and bereavement: is it stressful? Is it helpful?
Discussing end-of-life issues with terminally ill patients is often considered distressing and harmful. This study was conducted to assess whether interviewing terminally ill patients and their caregivers about death, dying, and bereavement is stressful and/or helpful. ⋯ Terminally ill patients and their caregivers can discuss death, dying, and bereavement in a structured interview with minimal stress and report that the interview was helpful. Institutional review boards should not preemptively restrict surveys with terminally ill patients without reliable evidence that they will be stressful or otherwise harmful.

The evidence for an association between alcohol consumption and risk of atrial fibrillation is conflicting. ⋯ Consumption of alcohol was associated with an increased risk of atrial fibrillation or flutter in men. In women, moderate consumption of alcohol did not seem to be associated with risk of atrial fibrillation or flutter.
