Objectives. To determine the association of medical marijuana laws (MMLs) with traffic fatality rates. Methods. Using data from the 1985-2014 Fatality Analysis Reporting System, we examined the association between MMLs and traffic fatalities in multilevel regression models while controlling for contemporaneous secular trends. We examined this association separately for each state enacting MMLs. We also evaluated the association between marijuana dispensaries and traffic fatalities. Results. On average, MML states had lower traffic fatality rates than non-MML states. Medical marijuana laws were associated with immediate reductions in traffic fatalities in those aged 15 to 24 and 25 to 44 years, and with additional yearly gradual reductions in those aged 25 to 44 years. However, state-specific results showed that only 7 states experienced post-MML reductions. Dispensaries were also associated with traffic fatality reductions in those aged 25 to 44 years. Conclusions. Both MMLs and dispensaries were associated with reductions in traffic fatalities, especially among those aged 25 to 44 years. State-specific analysis showed heterogeneity of the MML-traffic fatalities association, suggesting moderation by other local factors. These findings could influence policy decisions on the enactment or repealing of MMLs and how they are implemented. [ABSTRACT FROM AUTHOR]

Objectives. To evaluate the impact of the partial repeal of Michigan’s universal motorcycle helmet law on helmet use, fatalities, and head injuries. Methods. We compared helmet use rates and motorcycle crash fatality risk for the 12 months before and after the April 13, 2012, repeal with a statewide police-reported crash data set. We linked police-reported crashes to injured riders in a statewide trauma registry.We compared head injury before and after the repeal. Regression examined the effect of helmet use on fatality and head injury risk. Results. Helmet use decreased in crash (93.2% vs 70.8%; P < .001) and trauma data (91.1% vs 66.2%; P < .001) after the repeal. Although fatalities did not change overall (3.3% vs 3.2%; P = .87), head injuries (43.4% vs 49.6%; P < .05) and neurosurgical intervention increased (3.7% vs 6.5%; P < .05). Male gender (adjusted odds ratio [AOR] = 1.65), helmet nonuse (AOR = 1.84), alcohol intoxication (AOR = 11.31), intersection crashes (AOR = 1.62), and crashes at higher speed limits (AOR = 1.04) increased fatality risk. Helmet nonuse (AOR = 2.31) and alcohol intoxication (AOR = 2.81) increased odds of head injury. Conclusions. Michigan’s helmet law repeal resulted in a 24% to 27% helmet use decline among riders in crashes and a 14% increase in head injury. [ABSTRACT FROM AUTHOR]

We describe the patterns of coverage gains associated with the Affordable Care Act (ACA) expansions and use these patterns to assess the potential impact of alternative repeal or repeal and replace strategies because Congress and the president are weighing options to repeal or replace the ACA. We find that specific provisionsof the ACA, including the Medicaid expansion and the structure of premiumsubsidies, have been associated with large and robust gains in insurance coverage. We evaluate the impact of retaining dependent coverage and high-risk pool provisions and show, on the basis of the ACA experience, that these provisions would have little effect on coverage. We find that many replacement proposal components, including flat tax credits and maintaining cost savings provisions, could jeopardize the ability of many of the ACA's primary beneficiaries, as well as other Americans, to access coverage and care. By leading to a deterioration of the safety net, these strategies could also imperil population health activities. [ABSTRACT FROM AUTHOR]

The article discusses various rules which prevent transgender military recruits and personnel from serving in the U.S. armed forces as of 2014, focusing on the U.S. Don’t Ask, Don’t Tell Repeal of Act of 2010 and the use of American Psychiatric Association's "Diagnostic and Statistical Manual of Mental Disorders" (DSM) treatise on transgender people in military medical fitness criteria. It is noted that several U.S. allies such as Australia allow transgender military personnel to serve openly.
