RESUMEN

A quantitative, descriptive survey was conducted using Waterhouse's instrument, Survey of Sexuality-Related Nursing Practice. The purpose of this study was to examine the extent to which maternal/child and women's health nurses address sexuality in their practice and to assess the influence of select variables on that practice. A sample of maternal/child and women's health registered nurses (n = 130) was systematically selected from the 1995 Association of Women's Health, Obstetric and Neonatal Nurses' (AWHONN) District VII mailing list. Findings reveal incongruities in maternal/child and women's health nurses' perspectives and the incorporation of sexuality-related nursing interventions into practice.

RESUMEN

Replication-incompetent viral vectors are being developed for the gene therapy of cancer. Although some of these may eventually be proven to have significant localized antitumoral activity, none to date have been shown to infect and cause regression of established tumors following i.v. administration. Because cancer is a systemic disease in almost all fatal cases, the lack of i.v. efficacy is a major limitation to treatment with replication-incompetent viral vectors. ONYX-015 (d11520) is an attenuated adenovirus that replicates in and causes selective lysis of cancer cells. We carried out i.v. efficacy and distribution studies in nude mice with s.c. and intraparenchymal tumor xenografts. ONYX-015 infected and replicated efficiently within tumors following i.v. administration. Viral titers in livers were relatively high 3 h after administration but decreased rapidly, becoming undetectable after 24 h. Effective antitumor doses were not associated with hepatic toxicity. Viral replication within tumors was associated with regressions in several tumor models. Selectively replicating viruses like ONYX-015 hold promise as agents to treat metastatic cancer.

RESUMEN

CONTEXT: Injury is a major public health problem in Alaska, and alcohol consumption and injury death are associated. OBJECTIVE: To determine the association between injury death, particularly alcohol-related injury death, and alcohol availability in remote Alaska. DESIGN, SETTING, AND PARTICIPANTS: Survey using death certificate data and medical examiner records to compare mortality rates for total injury and alcohol-related injury during 1990 through 1993 among Alaskans aged 15 years and older who had resided in remote villages of fewer than 1000 persons. MAIN OUTCOME MEASURES: Rate ratios of injury death among residents of wet villages (ie, those without a restrictive alcohol law) as compared with injury death among residents of dry villages (ie, those with laws that prohibited the sale and importation of alcohol). RESULTS: Of 302 injury deaths, blood alcohol concentrations (BACs) were available for 200 deaths (66.2%). Of these, 130 (65.0%) had a BAC greater than or equal to 17 mmol/L (> or =80 mg/dL) and were, therefore, classified as alcohol related. The total injury mortality rate was greater among Alaska Natives from wet villages (rate ratio [RR],1.6; 95% confidence interval [CI], 1.3-2.1), whereas this difference was not present for nonnatives (RR, 1.1; 95% CI, 0.3-3.8). For Alaska Natives, the alcohol-related injury mortality rate was greater among residents of wet villages (RR, 2.7; 95% CI, 1.9-3.8) than among residents of dry villages. The strength of this association was greatest for deaths due to motor vehicle injury, homicide, and hypothermia. CONCLUSIONS: Although insufficient data existed to adjust for the effects of all potential confounders, residence in a wet village was associated with alcohol-related injury death among Alaska Native residents of remote Alaska villages. These findings indicate that measures limiting access to alcoholic beverages in this region may decrease alcohol-related injury deaths.

RESUMEN

OBJECTIVE: To test the hypothesis that Alaska Natives have fewer atherosclerotic lesions in the coronary arteries and aorta than nonnative Alaska residents. DESIGN: Systematic standardized collection and evaluation of coronary arteries and aortas collected at autopsy. SETTING: Forensic autopsy service in Alaska. SUBJECTS: One hundred thirty Alaska Natives and 115 Alaska nonnatives who underwent forensic autopsy between February 1989 and December 1993. INTERVENTION: None. MAIN OUTCOME MEASURES: Prevalence and extent of atherosclerotic lesions in the aortas and coronary arteries in both populations studied. RESULTS: Alaska Natives had significantly lower prevalence and extent of raised atherosclerotic lesions in the abdominal aorta and coronary arteries than nonnative Alaska residents. CONCLUSIONS: Differences in coronary heart disease mortality between Alaska Natives and nonnatives are, at least in part, the result of fewer atherosclerotic lesions in Alaska Natives.

RESUMEN

Low mortality from coronary heart disease (CHD) among Eskimos has been attributed to less atherosclerosis in the coronary arteries because of a high dietary intake of omega-3 fatty acids. Other investigators attribute this low mortality to the fact that Eskimos have a high mortality from other causes before middle age, when CHD is common. However, most studies have been epidemiological, either by death-certificate review or risk-factor evaluation. We evaluated the extent of atherosclerotic lesions in the coronary arteries and aortas from Alaska Natives. Standardised comparisons between samples from 103 Native and 101 non-native residents show that the extent of raised lesions increases with age in both groups, but the prevalence of raised lesions in native specimens was consistently lower than in those from non-natives. This difference was statistically significant. The data suggest that the differences in CHD mortality between Alaska Natives and non-natives are, at least in part, the result of less atherosclerosis in natives.

RESUMEN

We conducted a double-blind pilot study of 8 patients with established cerebral infarction to evaluate the effect of a single dose of amphetamine on recovery of motor function using the Fugl-Meyer scale. Four patients received amphetamine; the rest were given placebo. All underwent a session of physical therapy. Patients treated with amphetamine obtained greater increments in motor scores than the controls. Along with animal studies, these findings may allow the development of a pharmacological approach to stroke rehabilitation.

RESUMEN

This study establishes intratester reliability for all components of physical performance and intertester reliability for the total scores of upper and lower extremity motor performance in a cumulative numerical scoring system devised by Fugl-Meyer et al. Intertester reliability was found to be high for the total scores of upper and lower extremity motor performance. All intratester and intertester reliability coefficients were high and statistically significant. Establishing the reliability of the Fugl-Meyer method of assessing recovery of function following cerebrovascular accident has increased the usefulness of this method for clinical assessment and as a tool for the comparative analysis of the effectiveness of various therapeutic interventions.

RESUMEN

Because of the rising cesarean birth rate in the United States, renewed interest in vaginal delivery after prior abdominal operation has been evident. In a prospective collaborative study 789 patients were evaluated for inclusion into this investigation. Of the 717 subjects who entered the study 162 chose to attempt vaginal birth and 101 were successful. Desire for tubal sterilization and the lack of prior vaginal delivery were significant correlates of the group selecting repeat abdominal birth and of those who were unsuccessful when vaginal delivery was attempted. There were eight dehiscences and three uterine ruptures among the 717 patients and none was related to catastrophic outcome for the mother or neonate. Perinatal losses (12) were not related to uterine rupture or method of delivery. There were no significant differences in uterine disruption between patients selecting either route of delivery. Likewise ancillary factors such as a prior febrile puerperium (endometritis), number of prior cesarean births, low-vertical uterine incisions, recurrent operative indications, the use of epidural anesthesia, or oxytocin administration were not discriminating factors in whether women chose to attempt or were successful in completing vaginal delivery after prior abdominal birth. From our data vaginal birth after cesarean section appears to be safe if conducted in a carefully selected population that is closely monitored in a prospective manner.

RESUMEN

An American black family in whom hemoglobin J Baltimore and beta (+)-thalassemia genes coexisted is described. The proposita is a 23-year-old woman with a hemoglobin (Hb) level of 11.5 g/dl, microcytic, hypochromic indices, increased values of Hbs A2 and F, and alpha/non-alpha synthetic ratio of 1.52. Hbs A and J Baltimore (beta 16 Gly---Asp) constituted 12% and 81.3%, respectively, of her total hemoglobin. Her sister had a very similar peripheral blood picture, but Hbs A and J Baltimore constituted 6.8% and 85.5%, respectively, of her total hemoglobin, and the alpha/non-alpha synthetic ratio was 1.39. The mother had beta(+)-thalassemia trait only, a moderate degree of anemia, and greater synthetic imbalance (alpha/non-alpha raio of 1.73). These findings suggest that the presence of the Hb J Baltimore gene ameliorates the effects of a coexistent beta-thalassemia gene.

RESUMEN

Climacteric symptoms in the menopausal woman are perplexing to the physician. Recent literature concerning the relationship of estrogen to carcinogenesis has caused many women to discontinue this medication; thus, there is a need for an alternative therapy for the relief of these symptoms. The drug medroxyprogesterone acetate (Depo-Provera) was assessed in a double-blind, randomized, placebo-controlled study involving 48 subjects. Only one of the placebo-treated patients claimed any relief from climacteric symptoms while only two of the patients who received the study drug noted little or no relief (P < 0.0001). Relief from climacteric symptoms began at 4 to 7 days after entry into the study and extended for 8 to 20 weeks. The only side effects were withdrawal bleeding and a slight, transient weight gain. Depo-Provera appears to be a reliable substitute for estrogen in the treatment of climacteric symptoms. Further investigations with this medication seem indicated.

RESUMEN

It is evident that patients with sickle cell disease are now in an era when they can safely complete a pregnancy with a reasonable expectation of a good outcome for both the mother and baby. Although there are vast disagreements as to which techniques (both diagnostic and therapeutic) to employ, the use of individualized methods in various geographic areas will yield the best result. To conclusively answer the questions raised in this article, a large multi-center collaborative study must be performed. If randomized treatment regimens of "transfusion versus no transfusion" were carried out in such a study, the true risk of both approaches could be assessed. Moreover, with adequate follow-up studies many of the risks of each type of treatment could be evaluated. Only through such a large study will these controversies be resolved.

RESUMEN

Between 1903 and 1975 about 1 percent of climbers on Mount McKinley (Denali) and Mount Foraker in Alaska died. In 1976 a total of ten (1.7 percent) of 587 mountaineers died, but this rate of death was not significantly higher than previously. Nineteen percent of climbers in 1976 suffered major or minor injuries, illness or death. Acute mountain sickness (AMS), frostbite and fractures were common. Thirty-three rescues or retrievals of bodies were mounted at a cost of more than $82,000. Inexperience (particularly with arctic mountaineering), poor leadership, faulty equipment and undue reliance on rescue by helicopter contributed to the alarming incidence of accident, illness and death on big peaks in Mount McKinley National Park in 1976.

RESUMEN

A modified auxanographic carbohydrate assimilation procedure for the identification of medically important yeasts is described. This method employs a heavy inoculum of unstarved yeasts, autoclaved yeast assimilation medium, pour plates of shallow depth, and commercially available carbohydrate-impregnated disks. The accuracy of this procedure was established in a comparison with the Wickerham broth method.
