Statins and osteoporosis

June 26, 2000

NEW YORK, June 26 (Praxis Press) Experimental evidence has shown that the cholesterol-lowering statin drugs may increase bone formation. Chan and colleagues undertook a population-based case-control study at six health-maintenance organizations in the USA to investigate the relationship between statin use and fracture risk among older women. They selected 928 women over 60 years of age who had non-pathological fracture of the hip, humerus, distal tibia, wrist, or vertebrae and compared their sta

Stomach cancer risk

June 26, 2000

NEW YORK, June 26 (Praxis Press) Stomach cancer is thought to result from Helicobacter pylori infection, most common where socioeconomic conditions are poor. Leon and colleagues have found that mortality from stomach cancer among 65-74 year old men correlates with infant mortality in 27 countries and that the two factors are strongly related (see editorial, or paper). To perform the analysis the researchers obtained death rates from stomach cancer and other causes from a database of the World He

Acute chest syndrome

June 23, 2000

NEW YORK, June 23 (Praxis Press) Acute chest syndrome is the leading cause of death among patients with sickle cell disease, but its cause is largely unknown. To determine the cause of acute chest syndrome and its response to therapy, Vichinsky and colleagues performed a study of 671 episodes of the acute chest syndrome in 538 patients with sickle cell disease. They found that among patients with sickle cell disease, acute chest syndrome is commonly precipitated by fat embolism and infection, es

"African levels" of ill-health push the US health system to 37th rank

By | June 22, 2000

The World Health Organisation (WHO)'s World Health Report for the year 2000 faces health ministries head on, and refuses to take their data for granted. Instead, it makes its own statistical analysis of how well 191 different national health systems are functioning. Tables cover a wide range of indicators, but summing up performance into a single measure, the report ranks the massively costly US system way down the list.WHO's Chris Murray

A first postcard from biotechnological China

By | June 22, 2000

Does China need biotechnology? The answer from China seems to be an emphatic yes. We have only 7% of the world's land, and yet are feeding 22% of the world's population. China's per capita tillable land and per capita consumption of fresh water are both one-fourth those of the world's averages. It is estimated that our population will reach 1.6 billion by 2030 (from 1.3 billion now) and food consumption will reach 650 million tons, compared with present production of 500 million tons. On top of

NEW YORK, June 22 (Praxis Press) Exercise training in patients with chronic heart failure improves work capacity, but effects on central hemodynamic function are not well established. Hambrecht and colleagues assigned 73 men younger than 70 with chronic heart failure to an exercise program or to a physically inactive control group (see paper). For the first 2 weeks of the program, participants exercised on a bicycle ergometer for 10 minutes four to six times a day under hospital supervision. For

June 21, 2000

NEW YORK, June 21 (Praxis Press) A common disorder known as generalized anxiety disorder (GAD) lasts for a period of six months or more, but it is unknown whether the long term-use of a drug used to treat this disorder, venlafaxine XR (brand name Effexor), is safe or effective. A new study has found that venlafaxine XR is an effective for both the short- and long-term treatment of anxiety. Venlafaxine XR may be useful for the long-term treatment of GAD.
