The purpose of this research was to determine the incidence and prevalence of drug use, alcohol use, and the combination of drug and alcohol use among motor vehicle crash (MVC) victims admitted to a Level-1 trauma center. In a 90-day study, nearly two-thirds of trauma center admissions were victims of motor vehicle crashes. Blood and urine was collected from 168 MVC victims of whom 108 were identified as the driver in the crash. Toxicology results indicated that 65.7% of drivers tested positive for either commonly abused drugs or alcohol. More than half of the drivers tested positive for drugs (50.9%) other than alcohol, with one in four drivers testing positive for marijuana use. About one-third of those using drugs had also been drinking, but alcohol was detected in only 30.6% of all injured drivers. Within the total MVC patient pool, passenger drug/alcohol use was equivalent to the driver population; however, injured pedestrians had higher rates of alcohol only than other MVC victims. There were no significant differences in drug and alcohol use between MVCs and trauma admissions of other causes. Of the patients with positive toxicology results, less than half (42%) were referred for evaluation for substance abuse disorders. 相似文献

The comparative effect of 2 tranquilizing drugs (miltown and thorazine) upon conditioning in normal adults was investigated. Conditioning involved GSR to a noxious (shock) and positive (sexually stimulating picture) stimulus. Both tranquilizers were observed to be ineffective in affecting classical conditioning procedures when the noxious UCS was used. Only miltown effected conditioning in the predicted direction when the positive UCS was used. The results are related to the differential effect of each tranquilizer upon the nervous system.

The status of psychology in national health insurance is clouded in the minds of some Washington planners because the independent practice of psychology is identified with fee-for-service payment mechanisms, active treatment is identified with drug therapy rather than psychotherapy, and planners are unfamiliar with the nature and the scope of the practice of psychologists. Also, some feel that psychology is not equivalent in practice to psychiatry because psychologists are not integrated into the medical community and because psychologists do not prescribe drugs. These criticisms seem unfounded, since physicians and psychologists have regular consultations and psychologists see many patients who have previously been treated with psychotropic medications. Further, clinical experience indicates frequent therapeutic success by reducing or discontinuing medication rather than placing patients on psychotropics. Accordingly, a questionnaire was sent to the 87 members of the Cleveland Academy of Consulting Psychologists (CACP), requesting information concerning the prescribing of psychotropics and records of interprofessional consultations. The results are provided here. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Chemical safety of meat and meat products 总被引:3,自引:0,他引:3
Since the Second World War the consumer behaviour in developed countries changed drastically. Primarily there existed the demand for sufficient food after a period of starvation, afterwards the desire for higher quality was arising, whereas today most people ask for safe and healthy food with high quality. Therefore a united approach comprising consistent standards, sound science and robust controls is required to ensure consumers' health and to maintain consumers' confidence and satisfaction. Chemical analysis along the whole food chain downstream (tracking) from primary production to the consumer and upstream (tracing) from the consumer to primary production is an important prerequisite to ensure food safety and quality. In this frame the focus of the following paper is the “chemical safety of meat and meat products” taking into account inorganic as well as organic residues and contaminants, the use of nitrite in meat products, the incidence of veterinary drugs, as well as a Failure Mode and Effect Analysis (FMEA) system assessing (prioritizing) vulnerable food chain steps to decrease or eliminate vulnerability. 相似文献

The removal of beta blockers and psycho-active drugs was investigated in a representative conventional German WWTP by long-term measurement campaigns along different biological treatment processes. The activated sludge treatment with an elevated SRT of 18 d was the only process which led to a significant removal of certain beta blockers and psycho-active drugs. The removal efficiency was below 60% for all compounds except for the natural opium alkaloids codeine and morphine being removed by more than 80%. Primary biological transformation and sorption onto sludge as the main removal mechanisms were examined in lab-scale batch experiments. Sorption onto activated sludge was found to be negligible (<3%). The biological transformation could be described by pseudo-first order kinetics and the transformation constants kbiol were used to predict the removal of beta blockers and psycho-active drugs in an activated sludge unit with a model. For most compounds the removal efficiencies measured on the full-scale WWTP were within the 95% confidence intervals predicted by the model. The results from full-scale measurements and modeling indicate that biological transformation in the nitrification tank together with parameters such as the sludge retention time and the temperature is crucial regarding the biological transformation of beta blockers and psycho-active drugs in conventional WWTPs. 相似文献
