Why nurses smoke: a review of the literature.

The smoking behaviour of nurses has been widely debated in the context of their professional role and responsibilities. There has been much speculation about why nurses smoke and possible explanations include a stressful nursing environment, peer pressure and socio economic status and education. This paper provides an overview of the literature which offers insights into the reasons why nurses smoke and compares the findings from this literature with those studies examining the smoking behaviour of women in general and young women in particular. This review reveals that many students take up smoking before commencing their training and the factors which influence nurses smoking are similar to those that influence similar groups of females in the general population.

The incidence of smoking amongst nurses: a review of the literature.

Over the years there has been an ongoing debate about the implications of the smoking behaviour of nurses in relation to their own health and in the context of their professional role and responsibilities. However it is difficult to determine with any degree of accuracy the current incidence of smoking amongst nurses and most of the available research is based on small samples which embrace nurses of different levels and status. Very few recent studies in the United Kingdom or elsewhere have focused on this issue. A confused picture therefore emerges. This paper presents a critical overview of the literature and where appropriate provides data about the incidence of smoking in comparable groups of the general population.

Evaluating the effectiveness of a smoking cessation intervention designed for nurses.

The purpose of this study was to evaluate the effectiveness of offering an individualised approach to smoking cessation to qualified nurses and student nurses in Northern Ireland. Twenty-two qualified nurses and 32 student nurses enrolled in the intervention. A further 23 qualified nurses and 33 student nurses expressed interest in giving up smoking, but did not wish to be included in the intervention. They were assigned to the comparison group. Objective verification utilising salivary cotinine measurements of continuous abstinence at 6 months and 1 year demonstrated that 24% of student and qualified nurses in the intervention groups stopped smoking compared with 7% of those in the comparison groups. Both of these differences are statistically significant (Fisher's Exact Probability Test p = < 0.05). This suggests that the individualised approach as used in this study is an appropriate method of helping motivated nurses to quit.

Heart rate surges during REM sleep are associated with theta rhythm and PGO activity in cats.

Rapid eye movement (REM) sleep is characterized by periods of profound cardiac autonomic activation evident in heart rate surges in humans and canines. Our goals were to determine whether or not the heart rate surge phenomenon occurs in cats and to characterize concurrent central nervous system activity. Cortical and hippocampal electroencephalogram, electromyogram, electrooculogram, pontogeniculooccipital (PGO) waves, subcutaneous electrocardiogram, and respiration were recorded. Bouts of sinus tachycardia lasting >/=3.5 s achieved a rate of 210 beats/min and were present predominantly during REM sleep. Heart rate during the surges rose an average of 26.4% from 132.5 +/- 2.0 beats/min before the surge to 167.5 +/- 2.6 beats/min (P < 0.001) and returned to 130.7 +/- 2.6 beats/min (P < 0.001). The heart rate surges were invariably accompanied by increased incidence and frequency of hippocampal theta waves and increased PGO wave frequency and incidence of PGO wave clusters and eye movement clusters. The occurrence of surges was dramatically reduced from 0.11 +/- 0.03 to 0.01 +/- 0.01/15 s of REM sleep (P = 0.02) by atenolol (0.6 mg/kg iv), indicating that the phenomenon is beta(1)-adrenergically mediated. These findings suggest a coupling between central activation of cardiac sympathetic nerves and the generation of hippocampal theta waves and PGO activity.

Validity of adolescents' report of maternal age.

Examined the validity of adolescents' reports of their mother's age. Most research on the validity of self-report focuses on personal behaviors such as alcohol and substance use, or response bias due to social desirability. Few studies investigate the validity of adolescents reporting of nonsensitive information. Data from 80 mother-adolescent pairs were collected. The sample included 9th graders from four high school English classes, equal numbers of males and females, and 15% African Americans. The correlation between mothers' reports and youths' reports of mother's age was .99, and 95% of the youth were within a year of their mother's correct age. No race or gender differences were found. These results allow researchers to examine adolescent outcomes for youth born to teen mothers without the expense of also collecting data from their mothers. Results also suggest that adolescents' self-reports of other nonsensitive familial data may also be valid.

Impact of childhood brain injury on work and family finances.

Parents of children who suffer brain injuries are often surprised by the extent to which work and family finances are disrupted. In this paper, work and financial problems are described, predictors are identified, and ways to minimize problems are discussed. Eighty-two children treated at two Massachusetts trauma centres were given an extensive battery of medical, functional, and psychosocial tests during hospitalization. At 1 and 6 months post-discharge they were retested and their parents were surveyed about work and financial difficulties. Trouble maintaining regular work schedules and injury-related financial problems were common. At highest risk for work and financial problems were families of children with severe injuries who had four to nine impairments, along with children hospitalized > 2 weeks who were not discharged to home. Surprisingly, families with HMO coverage reported significantly fewer financial problems, and this relationship was not due to differences in socioeconomic status or injury severity. Health-care providers need to pay more attention to the potential impact of injury on work and family finances. Providers can help at-risk families muster child-care services, deal effectively with employers and insurance companies, and plan for the future.

Pediatric trauma: impact on work and family finances.

OBJECTIVES: National data now exist on incidence, prevalence, and cost of injury. However, the personal impact of injury on work and family finances has not been thoroughly studied. We examine the extent and nature of work and financial problems after pediatric trauma and identify predictors. Clinicians are alerted so they can better counsel parents about potential postinjury work and financial difficulties. METHODS: Staff collected comprehensive data on the acute care and short-term rehabilitation of 182 Massachusetts children with injuries. Consenting parents were surveyed and their children were given a battery of medical, functional, and psychosocial tests. Information on work and financial impact at 1 and 6 months postinjury was available from 120 parents. RESULTS: Given these children's generally mild injuries, the impact on work and family finances was remarkable. For many families work and financial problems were short-lived; however, for others serious problems remained at 6 months postdischarge. Families whose children were severely injured were at highest risk for work and financial problems. Middle-class parents and parents on public assistance or in our other insurance category reported more work and financial problems than those in health maintenance organizations. Long acute hospital stay and four or more impairments at discharge were also strong predictors. CONCLUSION: Childhood injury can lead to serious work and financial problems for families. Given the central role of the family in pediatric rehabilitation, clinicians and policymakers involved in acute trauma care and rehabilitation should pay greater attention to the financial repercussions of injury.

Familiality of cancer in Utah.

The Utah Population Database allows examination of the genetic relationships among the 35.7% of all cancer cases in the state that have genealogical records. Familial clustering of cancer is measured by the Genealogical Index of Familiality and is examined by site, and within site by age of onset, histology, and gender. Most cancer sites examined show excess familiality for all cases considered together. Subsets of individuals with certain characteristics showed unusually high levels of familial clustering, specifically lymphocytic leukemias and especially chronic lymphocytic leukemia, lobular breast cancer, early lip cancer, early melanoma, and female lung cancers of alveolar/adenoma histology. These may represent characteristics of the most penetrant forms of inherited susceptibilities, those which are enhanced by environmental factors, chance aggregations, rare inherited syndromes, or a combination of these factors.

Adolescent health: a report to the U.S. Congress.

This article reports findings from an assessment by the Office of Technology Assessment (OTA), an analytical arm of the U.S. Congress. In brief, OTA found the conventional wisdom that American adolescents as a group are so healthy that they do not require health and related services is not justified. Even more disturbing, U.S. adolescents often face formidable barriers in trying to obtain health care. OTA suggested that Congress could act to 1) increase adolescents' access to health care, most effectively by supporting school- or community-based comprehensive health services specifically for adolescents, 2) restructure and reinvigorate the federal role in adolescent health, most visibly by creating an office of adolescent health in the U.S. Executive branch, and 3) improve adolescents' social environments, by providing more support to the families of adolescents, limiting adolescents' access to firearms, supporting the expansion of recreational opportunities for adolescents, and further supporting opportunities for community service. Congressional actions taken since the release of OTA's report are summarized.

Variability of serum bile acid concentrations over time in dairy cattle, and effect of feed deprivation on the variability.

Twelve nonlactating dairy cows, free of signs of liver disease and with normal serum activities of liver-derived enzymes and normal liver biopsy tissue, were examined over a 72-hour period for serum total bile acid concentrations. The cattle were fed hay twice daily, and blood samples were obtained every hour for 24 hours, every other hour for 24 hours, then every hour for 24 hours. After 3 weeks, the study was repeated on 6 of the cattle, thus providing data for eighteen 72-hour periods. Serum bile acid concentration varied greatly over the 72 hours, with the range being from one third to 3 times the median. There were variations by as much as 60 mumol/L from 1 hour to the next. After another 3 weeks, 8 of the cattle were deprived of hay for 48 hours and then fed hay morning and afternoon of the third (last) day of the study. There was no significant reduction in bile acid concentration after withholding the hay, but the variability was reduced (P = 0.02) during the last 20 hours of the hay-deprivation period. In 3 ancillary studies, serum bile acid concentrations were examined over a 48-hour period in 2 cows in early lactation, 3 cows in midlactation, and two 6-month-old heifers. The cows were fed hay and grain twice daily, and the heifers were fed only hay twice daily. In comparison with values for the 12 nonlactating cows fed hay twice daily, mean serum bile acid concentration in the recently freshened cows was significantly (P < 0.002) higher (62.9 vs 22.0 mumol/L).(ABSTRACT TRUNCATED AT 250 WORDS)

Serum bile acid concentrations in clinically normal cattle: comparison by type, age, and stage of lactation.

Serum total bile acid concentrations were determined for various types and ages of cattle. There was extreme variability among all the cattle, but the variance was twice as large (0.50 vs 0.22 in logarithmic scale) for beef cattle than for dairy cattle. There was no significant difference in serum total bile acid concentrations between beef cattle and dairy cattle in midlactation. Values for calves < 6 weeks old and for 6-month-old heifers were significantly (P = < 0.05) lower than values for lactating dairy cows. The 5th to 95th percentile range of values (mumol/L) for beef cattle was 9 to 126; for lactating dairy cattle, 15 to 88; and for 6-month-old dairy heifers, 11 to 64.
