How Can and Do Australian Doctors Promote Physical Activity?

Background.Physical inactivity is recognized as an important public health issue. Yet little is known about doctors' knowledge, attitude, skills, and resources specifically relating to the promotion of physical activity. Our survey assessed the current practice, perceived desirable practice, confidence, and barriers related to the promotion of physical activity in family practice.Methods.A questionnaire was developed and distributed to all 1,228 family practitioners in Perth, Western Australia.Results.We received a 71% response (n= 789). Family practitioners are most likely to recommend walking to sedentary adults to improve fitness and they are aware of the major barriers to patients participating in physical activity. Doctors are less confident at providing specific advice on exercise and may require further skills, knowledge, and experience. Although they promote exercise to patients through verbal advice in the consultation, few use written materials or referral systems.Conclusions.There are significant differences between self-reports of current practice and perceived desirable practice in the promotion of physical activity by doctors. Future strategies need to address the self-efficacy of family physicians and involve resources of proven effectiveness. The potential of referral systems for supporting efforts to increase physical activity by Australians should be explored.     

A combined course of primary health care practice and family medicine at the University of Gezira

The community-based course presented is a longitudinal course running through four semesters in the Faculty of Medicine, University of Gezira, Sudan. Students combine their regular work in primary health care centres with attachments to a number of families in Wad Medani town. They continue to visit these families regularly throughout their entire medical course with the aim of studying them and helping them with some of their medical and psychosocial problems.     

An analysis of the deep social structure preventing the development of a national policy for children and families in the United States

The United States is one of the few economically developed nations without a national policy supporting children and their families. This paper suggests that the United States has a unique national ideology, based on the “Calvinistic Ethic,” which results in opposition to not only social programs for children and families, but to all government supported welfare programs. Such an ethic is not found in European countries. Finally, since the United States does not have a national family policy, millions of children and their families go without health care, lack social services, and suffer from inadequate economic supports.     

Meeting health care needs of women experiencing complications of miscarriage and unsafe abortion: USAID's postabortion care program

Each year, an estimated 210 million women become pregnant. Worldwide, more than one fourth of these pregnancies will end in abortion or an unplanned birth. While many abortions may result from the desire to delay or avoid pregnancy, 15% to 20% of pregnancies will end in miscarriage or stillbirth with some causative agents being malaria, HIV/AIDS, and physical violence. Postabortion care (PAC) is needed to provide treatment for complications caused by incomplete or spontaneous abortion and critical family planning counseling and services to prevent future unplanned pregnancies that may result in repeat abortions. In 2003, the United States Agency for International Development (USAID) initiated a 5-year strategy wherein seven countries were provided financial funding and technical assistance. Since 2003, more than 3000 women have been seen in health centers and health posts for PAC services; more than 14,000 community members have received messages on unsafe abortion; family planning, and complications of unsafe abortion and miscarriage; and more than 600 documents were reviewed for inclusion in a global PAC resource package. This package has been used for developing Cambodia's national PAC policy and for developing patient education materials and provider job aids in Cambodia and Tanzania. These promising methodologies will be replicated in other countries.     

耐药性癫(癎)患者颞叶中细胞周期依赖性蛋白激酶5的表达

目的 研究细胞周期依赖性蛋白激酶5(cyclin dependent kinases 5,CDK5)在耐药性癫(癎)患者颞叶中的表达,探索其在耐药性癫(癎)发病机制中的作用.方法 收集耐药性癫(癎)患者术后脑组织,用荧光定量PCR、免疫组化和Western blot 3种检测方法从基因和蛋白水平分别测定CDK5在耐药性癫(癎)患者颞叶中的表达,并与对照组进行比较.结果 荧光定量PCR发现CDK5 mRAN比对照组明显增加,免疫组化检测显示这种基因的蛋白表达产物主要分布在神经元轴突和胶质细胞中,Western blot检测在相对分子质量35 000处有一蛋白条带,并且可见实验组(颞叶和海马中分别为1.4293±0.1839和2.0733±0.4738)高于对照组(颞叶和海马中分别为0.9680±0.4147和1.403±0.6163,P＜0.05).结论 CDK5在耐药性癫(癎)患者颞叶中表达增强,提示他们可能参与了耐药性癫(癎)的形成.     

The ability of ‘family friendly’ organizational resources to predict work–family conflict and job and family satisfaction

The effectiveness of organizational interventions in reducing the adverse consequences of work–family conflict has produced mixed findings. This paper examines the relationship between the use of organizational ‘family friendly’ resources (such as crèche facilities, flexible working hours, and job sharing), with levels of work–family conflict, and job and family satisfaction over time. Using structural equation modelling, these associations were tested in 398 employed men and women who each completed a self‐report questionnaire administered on two occasions. The use of organizational interventions directly predicted increased levels of concurrent (Time 1) work–family interference and increased levels of subsequent (Time 2) job satisfaction. Both organizational interventions and family interventions (i.e. support) positively predicted subsequent family satisfaction. The research demonstrates that the provision of organizational ‘family‐friendly’ practices will produce improved psychological outcomes for employees. Copyright © 2005 John Wiley & Sons, Ltd.     

p38 MAPK对嗜酸性粒细胞和支气管上皮细胞共培养时细胞因子释放的调控作用

目的 了解嗜酸性粒细胞和支气管上皮细胞相互作用诱导细胞因子释放的p38 MAPK信号转导通路.方法 用CD16磁珠抗体分离外周血中嗜酸性粒细胞,以嗜酸性粒细胞和支气管上皮细胞(BEAS-2B)接触共培养为实验模型,观察SB 203580对细胞培养上清液中细胞因子浓度的影响.细胞因子浓度采用ELISA和流式细胞微珠方法测定.结果 SB 203580能够有效抑制BEAS-2B细胞释放IL-6、IL-8(P＜0.05)和嗜酸性粒细胞释放IL-8(P＜0.01).SB 203580对嗜酸性粒细胞与BEAS-2B细胞接触共培养诱导的IL-6、IL-8和IP-10释放具有显著抑制作用(P＜0.001).结论 嗜酸性粒细胞、BEAS-2B细胞单独或相互作用时均通过p38 MAPK信号转导通路释放细胞因子.
