OBJECTIVE--To determine whether counselling by health visitors is helpful in managing postnatal depression. DESIGN--Controlled, random order trial. SETTING--Health centres in Edinburgh and Livingston. PATIENTS--Sixty women identified as depressed by screening at six weeks post partum and by psychiatric interview at about 13 weeks post partum. Five women did not wish to participate, and a further five did not complete the trial. Age, social and obstetric factors, and diagnosis were similar in women who completed the trial and those who withdrew. INTERVENTION--Eight weekly counselling visits by health visitors who had been given a short training in counselling for postnatal depression. END POINT--Reduction of depression. MEASUREMENTS and main results--Standardised psychiatric interviews and a 10 point self report scale were used to identify depression before and after intervention. The psychiatrist was not told to which group women were allocated. After three months 18 (69%) of the 26 women in the treatment group had fully recovered compared with nine (38%) of the 24 in the control group. The difference between the groups was thus 32% (95% confidence interval 5 to 58). CONCLUSIONS--Counselling by health visitors is valuable in managing non-psychotic postnatal depression. 相似文献

The role of cytokines in oncology 总被引:1,自引:0,他引:1

The availability of sufficient quantities of recombinant human cytokines and promising preclinical data have led to their introduction into clinical trials. Cytokines have potential as new therapeutic agents in a variety of hematological disorders as well as in solid tumors. Only a few of the still increasing number of these glycoprotein hormones have been studied in humans so far, either as single agents or in combination with chemotherapy and other cytokines. Their clinical effects, beneficial role in supportive care, and use in the treatment of certain cancer patients are reviewed. 相似文献

The phenomenon of multidrug resistance in cancer is often associated with the overexpression of the ABC (ATP-binding cassette) transporters Pgp (P-glycoprotein) (ABCB1), MRP1 (multidrug resistance-associated protein 1) (ABCC1) and ABCG2 [BCRP (breast cancer resistance protein)]. Since the discovery of Pgp over 35 years ago, studies have convincingly linked ABC transporter expression to poor outcome in several cancer types, leading to the development of transporter inhibitors. Three generations of inhibitors later, we are still no closer to validating the 'Pgp hypothesis', the idea that increased chemotherapy efficacy can be achieved by inhibition of transporter-mediated efflux. In this chapter, we highlight the difficulties and past failures encountered in the development of clinical inhibitors of ABC transporters. We discuss the challenges that remain in our effort to exploit decades of work on ABC transporters in oncology. In learning from past mistakes, it is hoped that ABC transporters can be developed as targets for clinical intervention. 相似文献

For many years, Canadian academic health science centres have been active in international health. This brief review describes the activities of the Canadian Society for International Health, the Canadian University Consortium for Health in Development, and McGill, McMaster and Ottawa universities. Three principles are derived from these examples. Health must be placed in the broader context of development, and international health initiatives must be intersectoral. Canadian universities can make a distinctive and important contribution to health and development internationally, but this requires a clear commitment to scientific excellence and social responsibility. Finally, Canadian institutions, as representatives of the North, have much to learn through collaboration and partnerships with institutions in the South. 相似文献

Cancer has been the second most common cause of death in Canada for decades, and its nonsurgical management has largely been carried out by radiation oncologists for many years. Most of these specialists are not Canadian medical graduates, and the supply of suitably trained radiation oncologists is steadily diminishing in relation to the increasing numbers of patients referred to regional cancer centres. Consequently, the workload of each radiation oncologist has steadily increased to a level well beyond that recommended internationally, and it is still increasing. Unless more Canadian graduates can be attracted into the field, and unless more staff positions can be created in virtually all Canadian regional cancer centres, the high quality of patient care, teaching and research offered by radiation oncologists will suffer irreparably and will probably never recover to its former internationally recognized level. In this paper the author recommends ways in which to increase the number of radiation oncologists, though to be effective they will require the collaboration of provincial governments, medical schools, provincial cancer foundations and the medical profession. 相似文献
