Background
Aneurysmal subarachnoid haemorrhage (aSAH) is a devastating event with a frequently disabling outcome. Our aim was to develop a prognostic model to predict an ordinal clinical outcome at two months in patients with aSAH. 相似文献72.

The recent Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC) reiterated long-standing recommendations that Stage 1 hypertension (BP ≥ 140/90 mm Hg) without comorbidity should be treated initially with diuretics (DI) or beta blockers (BB). Yet market research suggests that many physicians prefer to use other drug classes, such as calcium channel blockers and ACE inhibitors.
OBJECTIVES: To explore the determinants of therapeutic choice in hypertension.
METHODS: We surveyed by mail a stratified random sample of 10,000 U.S. cardiologists, internists, and family/general practitioners. Physicians were queried about their practice environment and their knowledge, attitudes, and practices regarding antihypertensive therapy, including their choice of drugs to treat patients with specified clinical profiles. The probability that physicians would follow JNC guidelines Stage 1 hypertension was analyzed using multiple logistic regression with stepwise backward elimination to select variable with p < 0.001.
RESULTS: Completed surveys were received from 1,023 physicians. 86.7% prescribe drug therapy for Stage 1 hypertension, and 19.5% (22.5% of drug prescribers) limit their choices to DI and BB. Guideline conformity was higher among physicians who: practice in academic medical centrers; are older; are general practitioners (versus general internists); have smaller caseloads; have fewer hypertensive patients; have higher proportions of HMO, Medicaid, and uninsured patients; and experience more formulary restrictions. Cardiologists and family practitioners were less likely than internists to follow guidelines.
CONCLUSION: JNC guidelines are better accepted by academic physicians, older physicians who have more expenence using DI and BB, physicians with smaller caseloads and hence more time for follow-up and therapy adjustment, and physicians who face drug reimbursement constraints. 相似文献

To clarify the demography of delayed sleep phase syndrome (DSPS), non-24-h sleep-wake syndrome, and irregular sleep-wake pattern in Japan, a cross-sectional nationwide epidemiological survey was conducted. 1525 adults (age: 15-59 years) were randomly sampled from telephone directories, and they received screening questions over the phone. Persons who were suspected of having the disorders were requested to fill out the second questionnaire, and asked to keep a sleep log for 4 weeks. Diagnoses were made according to the International Classification of Sleep Disorders criteria. As a result, the prevalence of DSPS was estimated to be 0.13%. 相似文献

Abstract: In the current financial climate where resources in the National Health Service are becoming increasingly limited, it is essential that the role of the pediatric dermatology nurse specialist remains appreciated and supported. Our pediatric dermatology nurse specialist was first employed in September 2002 having had 6 years experience nursing children with a wide variety of dermatologic conditions prior to her employment. She achieved her pediatric community nursing degree in 2003 undertaking the nurse prescribing extended formulary course in 2006, her training history representative of many nurse specialists. We present the results of an audit highlighting how the employment of our pediatric dermatology nurse specialist has led to a decrease in hospital admissions as well as providing a significant positive impact on waiting lists. 相似文献

New agents for treatment of advanced transitional cell carcinoma 总被引:1,自引:1,他引:0
The prognosis for any patient with progressive or recurrentinvasive transitional cell carcinoma remains poor. In this context,the focus of clinical research in these invasive cancers concentrateson identifying systemic treatment options and new agents inorder to improve survival of patients. Cisplatin-based chemotherapyis standard treatment of patients with metastatic urothelialcancer; however, despite regimens as the cisplatingemcitabinecombination, the overall response rates vary between 40% and65%, with complete response in 15%25% with survivalsup to 16 months. This survival is frequently achieved with severeand life-threatening side effects. None the less, almost allresponding patients relapse within the first year; therefore,the need for development of new and tolerable agents is urgent.This review highlights some new active chemotherapeutic as newplatinum compounds (oxaliplatin, lobaplatin), gallium nitrate,ifosfamide, the antifolates piritrexim and pemetrexed (Alimta®,LY231514), vinflunine and molecular targeting agents such asfarnesyltransferase inhibitors (lonafarnib, R115777, SCH66336),ribozyme (RPI.4610), histone deacetylase inhibitor (CI-994)and monoclonal antibodies (epidermal growth factor receptor,Her 2/neu). Key words: transitional cell carcinoma, gallium nitrate, vinflunine, platinum compounds, antifolates, molecular targeting agents
