Ischemia on an exercise test (ET) is a known risk factor for cardiovascular mortality. However, the magnitude of risk of frequent premature ventricular contractions (PVCs) on ET is often overlooked. This analysis reveals that the quantitative additional mortality risk on ET presented by frequent PVCs is similar to ischemia. 相似文献

The Impact of Financial Crises on Labor Markets, Household Incomes, and Poverty: A Review of Evidence 总被引:1,自引:0,他引:1
The 1990s have witnessed several financial crises, of whichthe East Asia and Mexico tequila crises are perhaps the mostwell known. What impact have these crises had on labor markets,household incomes, and poverty? Total employment fell by muchless than production declines and even increased in some cases.However, these aggregates mask considerable churning in employmentacross sectors, employment status, and location. Economies thatexperienced the sharpest currency depreciations suffered thedeepest cuts in real wages, though deeper cuts in real wagesrelative to GDP were associated with smaller rises in unemployment.To some extent, families smoothed their incomes through increasedlabor force participation and private transfers, though thelimited evidence available suggests that wealthier familieswere better able to smooth consumption. The initial impact ofthe crises was on the urban corporate sector, but rural householdswere affected as well and in some instances suffered deeperlosses than did urban families. School enrollment declined,especially among poorer families, as did use of health facilities,but he impact on children's nutrition levels appears to vary.Crises have typically proved short-lived, but whether householdsplunged into poverty during a crisis are able to recover asthe economy does remains an open question. 相似文献

If your company operates in a developing country, AIDS is your business. While Africa has received the most attention, AIDS is also spreading swiftly in other parts of the world. Russia and Ukraine had the fastest-growing epidemics last year, and many experts believe China and India will suffer the next tidal wave of infection. Why should executives be concerned about AIDS? Because it is destroying the twin rationales of globalization strategy-cheap labor and fast-growing markets--in countries where people are heavily affected by the epidemic. Fortunately, investments in programs that prevent infection and provide treatment for employees who have HIV/AIDS are profitable for many businesses--that is, they lead to savings that outweigh the programs' costs. Due to the long latency period between HIV infection and the onset of AIDS symptoms, a company is not likely to see any of the costs of HIV/AIDS until five to ten years after an employee is infected. But executives can calculate the present value of epidemic-related costs by using the discount rate to weigh each cost according to its expected timing. That allows companies to think about expenses on HIV/AIDS prevention and treatment programs as investments rather than merely as costs. The authors found that the annual cost of AIDS to six corporations in South Africa and Botswana ranged from 0.4% to 5.9% of the wage bill. All six companies would have earned positive returns on their investments if they had provided employees with free treatment for HIV/AIDS in the form of highly active antiretroviral therapy (HAART), according to the mathematical model the authors used. The annual reduction in the AIDS "tax" would have been as much as 40.4%. The authors' conclusion? Fighting AIDS not only helps those infected; it also makes good business sense. 相似文献

Prostate cancer is the most common internal cancer in American males. There are many variables that effect prognosis, with the Gleason scoring system being one of the most important factors. There is controversy regarding the ideal treatment in various subsets of prostate cancer patients. Posttreatment prostate specific antigen values have prognostic significance. 相似文献

The process of integrating health and welfare plans during an M&A is challenging. At the same time, it can be exciting and possibly even desirable for the growth of a benefits plan. An M&A can be the vehicle for ushering in changes that would not be possible under the current employers' plans. It gives additional leverage with vendors. It may supply the momentum to clear up nagging problems or to address underlying benefits concerns. 相似文献
