Significant concerns over the health,social and economic burdens of the two most common,and frequently co-misused drugs of abuse,alcohol and tobacco,has encouraged focused but separate health promotion and disease prevention policies.However,this separation of focus means that while individuals who present with alcohol-related problems are increasingly supported to attain and maintain abstinence from alcohol they are not routinely assisted to refrain from smoking.This is tragically inopportune as alcohol and tobacco have an established"synergistic"effect on aerodigestive cancer risk.Moreover,even when patients successfully tackle their alcohol problems they remain at increased risk for developing these cancers,especially if they continue to smoke.A case series is presented together with a discussion on how service provision for co-misuse could be improved to obviate aerodigestive cancer risk.Given the prevalence of alcohol and tobacco use in the United Kingdom,these observations may have far reaching implications for the individual,health provider(s)and wider society. 展开更多

The crisis of 2008 has shown the unsustainability of the global imbalances centered on the US-China symbiotic relationship that characterized the previous decade. This has revived the so-called growth-rebalancing debate. In particular, the new emerging consensus calls for a re-orientation of the US economy away from consumption and toward exports, and for policy shifts that can help China to reduce its dependence on external demandand inefficiently high rates of capital accumulation. We discuss the economic and political feasibility of the proposed patterns of re-adjustment by focusing on the short-term and long-term trade-offs faced by the policy-makers. We argue that the rebalancing will be gradual and partial because of the costs associated with a radical shift in the growth models adopted by both countries. We believe that this scenario will be consistent with a world economy expanding at lower rates than over the past decade. 展开更多
