The effects of cocaine on Y-maze activity and heart rate have been examined in four inbred strains of mouse (BALB, C57BL, C3H and DBA). In addition, brain [3H]-cocaine concentrations were measured at the time of maximal response to cocaine. Cocaine produced a dose-related increase in Y-maze cross activity in C3H, DBA and C57BL, with C3H mice being(More)
The possibility that nicotine-induced corticosterone (CCS) release regulates nicotine sensitivity was investigated in female mice of the C3H strain. Adrenalectomy (ADX) resulted in an increase in nicotine sensitivity as measured in a number of physiological and behavioral tests. In ADX animals, chronic CCS (100 micrograms/ml) administered in the drinking(More)
Causal modeling was used to explore the processes by which individual characteristics, job satisfaction, and intention to quit explain turnover among nursing personnel in 29 Department of Veterans Affairs (VA) long-term psychiatric settings. The sample consisted of 1,106 registered nurses (RNs), licensed practical nurses (LPNs), and nurses' aides. We(More)
Shoulder dislocation is the most frequent dislocation treated in the Emergency Department (ED). Orthopedic literature cites up to a 55% incidence of fracture, vascular or neurologic injury associated with this injury, but these studies suffer from referral bias. No large ED series has been reported. This retrospective chart review was conducted in an(More)
The cumulative incidence of microalbuminuria from onset up to 15 years of Type 1 (insulin-dependent) diabetes mellitus and the relative importance of age, duration, blood pressure and metabolic control for subsequent microalbuminuria was studied in 156 children. Urinary albumin excretion and HbA1c were followed at 3-month intervals from onset and systolic(More)
BACKGROUND Although randomized trials suggest that transfer for primary percutaneous coronary intervention (X-PCI) in ST-segment-elevation myocardial infarction is superior to onsite fibrinolytic therapy (O-FT), the generalizability of these findings to routine clinical practice is unclear because door-to-balloon (XDB) times are rapid in randomized trials(More)
OBJECTIVE Characteristics of individual mental health providers and of treatment settings were examined to determine their effects on providers' expectations about the improvement of patients with serious mental illness. METHODS The sample consisted of 1,567 treatment providers working in 107 inpatient and outpatient units or programs in 29 Veterans(More)
The electrocardiogram (ECG) may be entirely normal in the patient with pulmonary embolism (P/E); alternatively, any number of rhythm and/or morphologic abnormalities may be observed in such a patient. The abnormal ECG may deviate from the norm with alterations in rhythm, in conduction, in axis of the QRS complex, and in the morphology of the P wave, QRS(More)
Acute myocardial infarction (AMI) is one of many causes of electrocardiographic ST segment elevation (STE) in ED chest pain (CP) patients; at times, the electrocardiographic diagnosis may be difficult. Coexistent ST segment depression has been reported to assist in the differentiation of non-infarction causes of STE from AMI-related ST segment elevation.(More)
OBJECTIVE The study aim was to determine the prevalence of repeated assaults on staff and other patients and characteristics of patients who commit repeated assaults in the Veterans Health Administration of the Department of Veterans Affairs. METHODS Patients in VA medical centers and freestanding outpatient clinics who committed two or more assaults in(More)
