An important operational aspect of Syringe Exchange Programmes (SEPs) is the venue of service delivery. This report describes the programmatic features of the Sacramento Area Needle Exchange (SANE), an illegal SEP operating in California, USA. SANE utilises “satellite exchangers” to distribute the bulk of its syringes and HIV risk reduction supplies. Advantages of relying primarily on Designated Exchangers (DE) for delivery of SEP services are that it: (1) allows for coverage of a large geographical area; (2) keeps operational cost low; (3) provides syringes to clients who may not want to or cannot use fixed site programmes; (4) limits the possibility of detection of programme personnel and clients by law enforcement. Limitations are that: (1) it is not as conducive as fixed sites to providing a wide range of ancillary services; (2) it may not be optimal for drug users who do not want to be reliant on other people for access to syringes; (3) those who receive services from a satellite exchanger may not derive as much counselling and referral services as direct exchangers. The lack of legal status, political support and adequate funding threatens the programme’s existence. 相似文献

Intragastric balloons have been suggested as a treatment for severe obesity, a degree of obesity associated with a relatively greater eating disorder or lack of control of energy balance. The premises that 250-500-ml balloons are able to simulate "satiety" in a 1700-ml stomach sufficiently to cause weight loss, that the stomach will not stretch to accommodate such a besoar (with or without ulcerating), and that behavioral modification is cost-effective in weight control in this population have not been corroborated. Experience from gastric restrictive surgery has demonstrated the conceptual failure of gastric satiety as a means of achieving and sustaining weight loss in a substantial percentage of morbidly obese patients. Other methods are needed to reduce the increased morbidity and mortality of severe obesity. 相似文献
