Achieving a tobacco-free military requires rethinking current perceptions of service members' tobacco use and unmasking the forces perpetuating those perceptions. Prohibiting tobacco use would be entirely consistent with other military requirements regarding health.

Outcomes for truncus arteriosus repair are impacted significantly by the severity of truncal valve dysfunction. When satisfactory repair of the regurgitant truncal valve is unattainable, replacement is required. Given our experience in children with stentless porcine xenografts in the aortic position and the incidence of early valve failure for aortic homografts in infants, we replaced a severely regurgitant truncal valve with a full-root porcine xenograft in a 3-month-old infant. The initial and early result are encouraging, suggesting that the stentless porcine xenograft may be considered an option in cases where primary repair of the truncal (or aortic) valve is not possible.

Episodic drug use and binge drinking are associated with HIV risk among substance-using men who have sex with men (SUMSM), yet no evidence-based interventions exist for these men. We adapted personalized cognitive counseling (PCC) to address self-justifications for high-risk sex among HIV-negative, episodic SUMSM, then randomized men to PCC (n = 162) with HIV testing or control (n = 164) with HIV testing alone. No significant between-group differences were found in the three primary study outcomes: number of unprotected anal intercourse events (UAI), number of UAI partners, and UAI with three most recent non-primary partners. In a planned subgroup analysis of non-substance dependent men, there were significant reductions in UAI with most recent non-primary partners among PCC participants (RR = 0.56; 95 %CI 0.34-0.92; P = 0.02). We did not find evidence that PCC reduced sexual risk behaviors overall, but observed significant reductions in UAI events among non-dependent SUMSM. PCC may be beneficial among SUMSM screening negative for substance dependence.
