Predictors of worsening insulin sensitivity in postmenopausal women.

OBJECTIVE: The purpose of this study was to determine predictors of worsening insulin sensitivity in postmenopausal women. STUDY DESIGN: Seventy-one nonobese postmenopausal women were assigned randomly to receive hormone replacement therapy (conjugated estrogens, 0.625 mg, plus medroxyprogesterone acetate, 2.5 mg) or placebo daily for 1 year (34 women received hormone replacement therapy, and 37 women received placebo). At baseline and 12 months, the women received a computed tomography scan at the L4-L5 vertebral disk space, a dual x-ray absorptiometry scan, a euglycemic hyperinsulinemic clamp to measure insulin sensitivity, and a lipid profile. Declining insulin sensitivity was defined as the largest quartile change in insulin sensitivity in the women who received the placebo (-1.42 mg/min/kg lean body mass). RESULTS: By univariate analysis, we found that significant predictors of worsening insulin sensitivity were the use of hormone replacement therapy, baseline insulin sensitivity, a younger age, and <10 years since menopause. By logistic regression, we determined that hormone replacement therapy use and higher baseline insulin sensitivity were independent predictors of worsening insulin sensitivity. CONCLUSION: The use of hormone replacement therapy and baseline insulin sensitivity are significant independent predictors of the development of worsening insulin sensitivity in postmenopausal women.

Epidermolysis bullosa: pathophysiology and nursing care.

Epidermolysis bullosa (EB) is defined as a group of skin disorders that presents as blistering of the skin in varying degrees of severity. Most cases are inherited, but rare cases may be acquired. There are three main types: simplex, junctional, and dystrophic. The dermal-epidermal junction of the newborn skin is a vital area of attachment. Any defects in the components that comprise this junction can lead to fragility of the skin. EB diagnosis and testing can be per formed both prenatally and postnatally. There is no cure for EB. Treatment revolves around supportive care and prevention of complications. The NICU nurse plays an important role on the multidisciplinary team as primary caregiver to the infant and educator to the family.

Psychosocial and behavioral functioning among pediatric brain tumor survivors.

OBJECTIVE: To describe the psychosocial and behavioral functioning, as described by patient, parent and teacher, of a cohort of adolescents who have been previously treated for a brain tumor. METHODS: A cohort of 32 patients, 12-18 years old, were evaluated between 1 and 5 years post-treatment for brain tumor during the patient's regularly scheduled follow-up clinic appointment at the Dana-Farber Cancer Institute. The Self-Report questionnaire and the Parent-Report of the Behavioral Assessment System for Children (BASC) were administered to the patient and to one of the patient's parents, respectively. In addition, the BASC Teacher-Report was completed by the patient's teacher. Descriptive statistics were generated; binomial distribution analyses were carried out to assess whether the proportion of individuals with impaired performance on each measure exceeded normative expectations. RESULTS: Comparison of the proportion of patients with elevated scores to normative expectations indicated no excess of elevated scores on any of the BASC scales of the Self-Report. However, parents endorsed items in the areas of attention problems and leadership; teachers endorsed items concerning learning problems; and both parents and teachers endorsed items indicative of somatization behaviors. CONCLUSIONS: Parent and teacher feedback indicate some level of psychosocial and behavioral morbidity for adolescents treated for a brain tumor; this finding contrasts with adolescent Self-Report indicating no difficulties in behavioral and psychosocial functioning. The extent to which these vulnerabilities impact quality of life and the discrepancy between reporters should be assessed in follow-up studies with a larger cohort of patients.
