The Enhancing Patient Prenatal Education study tested the feasibility and educational impact of an interactive program for patient prenatal genetic screening and testing education. Patients at two private practices and one public health clinic participated (N = 207). The program collected knowledge and measures of anxiety before and after use of the tool. Time in various prenatal visit activities was collected prior to and after the introduction of the education tool. Providers completed an assessment of their experiences with patients who had used the program. Results indicate that patient knowledge significantly increased from pre to post (p = .0001) with no increase in anxiety (p = .31). Time in clinic activities, including overall visit time, increased. A majority of providers indicated that the program disrupted clinic flow. This assessment suggests that the program increases patient knowledge and does not increase patient anxiety. However, challenges remain to using this program in a clinic setting. 相似文献
Benign strictures of the biliary ducts are treated surgically in 90% of cases. Usually they are caused by trauma to the choledochous duct during gallbladder operations. Younger patients are frequently affected and, particularly if the strictures go untreated, can suffer from secondary complications such as cholangitis or secondary biliary cirrhosis with the serious dangers of portal hypertension and even hepatic failure and death. Although immediate treatment by end-to-end anastomosis has sometimes been described, this method is reasonable only for smooth cuts to the choledochous duct. Good long-term results have been achieved in 86% of cases with Roux-en-Y hepaticojejunostomy. In general, the best way to avoid complications is the all-important surgical maxim of correct indication for the primary operation. The best course is to limit the decision for surgery to symptomatic gallstones. 相似文献
Background: Dreaming reported after anesthesia remains a poorly understood phenomenon. Dreaming may be related to light anesthesia and represent near-miss awareness. However, few studies have assessed the relation between dreaming and depth of anesthesia, and their results were inconclusive. Therefore, the authors tested the hypothesis that dreaming during anesthesia is associated with light anesthesia, as evidenced by higher Bispectral Index values during maintenance of anesthesia.
Methods: With approval, 300 consenting healthy patients, aged 18-50 yr, presenting for elective surgery requiring relaxant general anesthesia with a broad range of agents were studied. Patients were interviewed on emergence and 2-4 h postoperatively. The Bispectral Index was recorded from induction until the first interview. Dream content and form were also assessed.
Results: Dreaming was reported by 22% of patients on emergence. There was no difference between dreamers and nondreamers in median Bispectral Index values during maintenance (37 [23-55] vs. 38 [20-59]; P = 0.68) or the time at Bispectral Index values greater than 60 (0 [0-7] vs. 0 [0-31] min; P = 0.38). Dreamers tended to be younger and male, to have high home dream recall, to receive propofol maintenance or regional anesthesia, and to open their eyes sooner after surgery. Most dreams were similar to dreams of sleep and were pleasant, and the content was unrelated to surgery. 相似文献
AMPA receptor potentiators enhance AMPA receptor-mediated glutamatergic neurotransmission and may have therapeutic potential as cognitive enhancers or antidepressants. The anatomical basis for the action of AMPA receptor potentiators is unknown. The aim of this study was to determine the effects of the biarylpropylsulfonamide AMPA receptor potentiator, LY404187 (0.05 to 5 mg/kg subcutaneously), upon cerebral glucose utilization and c-fos expression using 14C-2-deoxglucose autoradiography and c-fos immunocytochemistry. LY404187 (0.5 mg/kg) produced significant elevations in glucose utilization in 28 of the 52 anatomical regions analyzed, which included rostral neocortical areas and the hippocampus, as well the dorsal raphe nucleus, lateral habenula, and locus coeruleus. No significant decreases in glucose utilization were observed in any region after LY404187 administration. The increases in glucose utilization with LY404187 (0.5 mg/kg) were blocked by pretreatment with the AMPA receptor antagonist LY293558 (25 mg/kg), indicating that LY404187 acts through AMPA receptor-mediated mechanisms. LY404187 (0.5 mg/kg) also produced increases in c-fos immunoreactivity in the cortex, locus coeruleus, and the dorsal raphe nucleus. These studies demonstrate neuronal activation in key brain areas that are associated with memory processes and thus provide an anatomical basis for the cognitive enhancing effects of AMPA receptor potentiators. 相似文献
Recent evidence suggests that heroin users in the UK are 16 times more likely to die than otherwise expected, although causes of death are varied. The present investigation examines deaths of heroin users at a large Scottish general practice over a four-year period prior to 1 July 1985. A mortality rate of 9.72 per 1000 heroin-user patients per year was observed, roughly half that previously reported, although this difference did not prove to be statistically significant. A higher proportion of the observed deaths were attributed to heroin, and fewer to the misuse of other drugs, and it is speculated that this may reflect the practice's policy of not prescribing opiates to heroin users. Factors associated with heroin-user deaths are examined and areas identified where general practitioners may help to avert some of these deaths. 相似文献
BACKGROUND: Numerous longitudinal studies have revealed that depression following an acute cardiac event poses a risk factor for poor cardiac outcomes. It is therefore important to identify modifiable predictors of depression in order to develop a variety of interventions with this population. AIMS: The aim of the present research was to determine whether the relationship between optimism and depressive symptoms was mediated by self-reported quality of life (QOL) in acute coronary syndrome patients. METHODS: Two weeks following hospital discharge (Time 1) 59 participants completed a self-report questionnaire. Four weeks later (Time 2), 49 of these participants completed the same questionnaire. RESULTS: At Time 1, the relationship between optimism and depressive symptoms was partially mediated by functional QOL and symptom QOL. Furthermore, the relationship between Time 1 optimism and Time 2 depressive symptoms was partially mediated by Time 1 functional QOL. When each of the Time 1 variables were used to predict Time 2 depressive symptoms, only optimism continued to predict depressive symptoms over and above the influence of Time 1 depressive symptoms and other covariates. CONCLUSION: These findings suggest the underlying importance of optimism in influencing depressive symptoms in acute coronary syndrome patients, and indicate that optimism and perceptions of functional QOL may be a possible rehabilitation target for this population. 相似文献
