There have been changes in the national policy regarding population growth in Malaysia from 1982. This report studies the changes in contraceptive practice among the three racial groups in this country, i.e. Malays, Chinese and Indians, over a 5-year period with an interval of 10 years. This is a retrospective study based on the attendance at the same family planning clinic in an urban setting. The striking change noted is the change in the racial composition of contraceptive usage in the two study periods with a shift from the Chinese being predominant in 1975-1979 to Malays in 1985-1989. There was no change among the numbers of Indians using contraception. The results also reveal a significant trend of change for users of the pill and those undergoing sterilization. There were no significant changes in IUD, condom and injectable usage. The study demonstrates how national policies, level of education and rural urban migration can significantly alter contraceptive practice.
PIP: Long term use of low doses of combination oral contraceptives appears to increase plasminogen level, thereby increasing fibrinolytic activity and reducing the risk of thromboembolism. Blood levels of plasminogen, tissue plasminogen activator (tPA), and plasminogen activator inhibitor (PAI), were measured before and after stress (5 minutes of stair climbing) in a group of 30 women, 23-40 years old, who had taken 30 mcg of ethinyl estradiol with 150 mcg of desogestrel or levonorgestrel for at least 1 year. Similar measurements were taken from a control group of 30 women matched for age, height, and weight. Plasminogen and tPA levels in both groups increased significantly after exercise. The level of PAI did not change significantly with stress in either group. The level of plasminogen was significantly higher in the group taking contraceptives, whether before or after exercise, when compared to the control group. Levels of tPA and PAI, although slightly increased in the oral contraceptive group, were not significantly different between the two groups. The increase in plasminogen may be due to the estrogen component of the contraceptives. Stress seems to increase fibrinolytic response.
A key determinant of breast cancer outcome in any population is the degree to which cancers are detected at early stages of disease. Populations in which cancers are detected at earlier stages have lower breast cancer mortality rates. The Breast Health Global Initiative (BHGI) held its third Global Summit in Budapest, Hungary in October 2007, bringing together internationally recognized experts to address the implementation of breast healthcare guidelines for early detection, diagnosis, and treatment in low- and middle-income countries (LMCs). A multidisciplinary panel of experts specifically addressed the implementation of BHGI guidelines for the early detection of disease as they related to resource allocation for public education and awareness, cancer detection methods, and evaluation goals. Public education and awareness are the key first steps, because early detection programs cannot be successful if the public is unaware of the value of early detection. The effectiveness and efficiency of screening modalities, including screening mammography, clinical breast examination (CBE), and breast self-examination, were reviewed in the context of resource availability and population-based need by the panel. Social and cultural barriers should be considered when early detection programs are being established, and the evaluation of early detection programs should include the use of well developed, methodologically sound process metrics to determine the effectiveness of program implementation. The approach and scope of any screening program will determine the success of any early detection program as measured by cancer stage at diagnosis and will drive the breadth of resource allocation needed for program implementation.
