Radiation therapy in breast conservation patients and postmastectomy.

Radiation has played a continuous but changing role in the management of breast cancer. At Memorial Hospital, the past 10 years have seen a marked increase in breast conserving therapy, and changing indications for postmastectomy adjuvant radiation.     

Pregnancy and epilepsy: nursing implications

Pregnant women with epilepsy have a greater risk for complications of pregnancy and adverse pregnancy outcomes. Problems that may arise during the course of pregnancy include an increase in seizure frequency, reduction of serum antiepileptic drug levels, and an increase in bleeding during pregnancy and after delivery. The infant of an epileptic mother is at twice the risk of infants in the general population to have a major malformation, and the risk for perinatal death is 1.2 to 3 times greater. Despite these facts, at least 90% of women with epilepsy have a normal pregnancy and deliver a normal infant. The pregnant woman with epilepsy may minimize the risk of adverse outcome by taking measures to ensure an optimal prenatal course. The neuroscience nurse can provide these clients with accurate information regarding pregnancy and epilepsy and can review measures that may be taken to reduce chances of an unfavorable outcome.     

Using international children's literature in the content areas

This article presents ways in which the development of children's language arts skills, cognitive knowledge and emotional growth are fostered through the use of international children's literature to teach a content area. A unit of study is described, including activities and books that might be used as children do a study of nocturnal animals.     

Lipoprotein particle abnormalities and the impaired lipolysis in renal insufficiency.

BACKGROUND: Increased concentrations of very low- (VLDL) and intermediate-density (IDL) lipoproteins in chronic renal failure (CRF) are thought to result from a defect(s) in degradation of plasma triglyceride (TG)-rich lipoproteins. The purpose of this study was to identify lipoprotein abnormalities associated with the reduced lipolytic rate constant, k1, of combined VLDL and IDL substrate from renal patients and asymptomatic controls. METHODS: The VLDL + IDL were isolated from 18 predialytic patients (CRF-I), 8 patients on hemodialysis (CRF-II) and 10 asymptomatic controls. The lipolytic rate constant (k1) of VLDL + IDL was measured by an assay using bovine milk lipoprotein lipase and determination of TG before and after incubation by gas chromatography (GC). Neutral lipids were measured by GC and apolipoproteins by electroimmunoassays; the apolipoprotein-defined TG-rich lipoproteins including Lp-B:C, Lp-B:C:E and Lp-A-II:B:C:D:E were determined by immunoaffinity chromatography. RESULTS: The k1 values of VLDL + IDL were significantly (P < 0.001) lower in CRF-I and CRF-II patients (0.0341 and 0.0352 min-1, respectively) than controls (0.0515 min-1). The levels of apolipoproteins B, C-III and E, and TG-rich Lp-B:C, Lp-B:C:E and Lp-A-II:B:C:D:E particles normalized to 100 mg TG per VLDL + IDL were significantly higher in both groups of CRF patients than in controls. All three TG-rich lipoproteins were characterized by significantly increased percent contents of free (FC) and esterified (CE) cholesterol and a decreased percentage of TG. The k1 values of the combined CRF-I and CRF-II patient groups showed significant negative correlations (P < 0.001) with FC (r=-0.81) and CE (r=-0.63) and a positive correlation with TG (r=0.72). Among lipoprotein particles, only Lp-A-II:B:C:D:E levels showed a significant negative correlation with k1 values (r=-0.47, P < 0.03). CONCLUSIONS: This study shows that the abnormal neutral lipid composition of all three TG-rich lipoprotein particles and increased concentrations of Lp-A-II:B:C:D:E particles represent the main factors affecting the in vitro lipolytic rates of VLDL + IDL substrate in both the CRF patients before dialysis and patients on hemodialysis.     

Problems with a ‘target’ approach to access in primary care: a qualitative study

We report an analysis of the qualitative phase of a study of patients' and carers' views of primary care services, focusing on their experiences of access to face-to-face general practitioner (GP) consultations during the period when new access policies were being implemented. Practices interpreted the new policy in various ways; restricted interpretations, including restriction of access to telephone booking, could cause distress to patients. Patients and carers welcomed flexible interpretations of the policy that offered choice, such as a choice of GP, or of booking in advance.
