Are tri-ethnic low-income women with breast cancer effective teachers of the importance of breast cancer screening to their first-degree relatives? Results from a randomized clinical trial.

The purpose of this study was to determine the efficacy of women with breast cancer as teachers of the importance of breast cancer screening to their first-degree female relatives. The sample was restricted to low-income working age women recruited from four hospitals. The study design was a randomized clinical trial. At each hospital, breast cancer patients (probands) were randomized into one of two study groups: (i) intensive, individual educational training on breast cancer screening or (ii) standard clinic education on breast cancer screening. The probands were instructed to teach at least one of their first-degree female relatives (21+ years of age) about breast cancer screening techniques. Three to six months after the enrollment of the probands, their relatives were contacted by telephone to determine breast cancer screening practices. A total of 79 probands and 96 relatives participated in the study. Relatives in the education group when compared with the control group were: 1.25 times more likely to have clinical breast examination (p = 0.005), 2.83 times more likely to have scheduled a clinical breast examination (p = 0.046), and, 1.36 times more likely to have been told about performing breast self-examination (p = 0.05). Additionally, relatives in the education group were more likely to have received a pamphlet on breast cancer screening (RR = 1.58, p = 0.009) and have discussed the importance of breast cancer screening (RR = 1.33, p = 0.020) from the proband. Special education training did not impact mammography utilization of the relatives. From these findings, a tri-ethnic group of low-income women with breast cancer can be effective teachers of breast cancer screening practices, at least for promoting clinical breast examination and transmitting messaging for performance of breast self-examination if given the adequate training.

Easing the burden on health departments: a cost-effective method for public health nurses to increase private sector participation in the early and periodic screening, diagnosis, and treatment program.

Federal legislation requires states to increase use of the early and periodic screening, diagnosis, and treatment (EPSDT) program. The program provides comprehensive health services to children from low-income families on Medicaid and has been shown to improve health and reduce health care costs. Health departments and public health nurses (PHNs) bear a major burden conducting EPSDT screenings because many private physicians choose not to provide these services. Given scarce resources, health departments alone may be unable to meet the mandate for increased EPSDT services. Thus PHNs concerned about children's access to health care may have to encourage provision of EPSDT through the private sector. This project, phase I of the federally funded Healthy Kids Project to increase EPSDT use in rural areas of North Carolina, established the cost-effectiveness of a mailed intervention to recruit private physicians to do EPSDT screens that exceeded the capacity of health departments. The intervention, consisting of a personal letter, journal article, and pamphlet, was sent to all 73 primary care physicians in six rural counties. Before the mailing, 15 (21%) of the 73 physicians were willing to provide EPSDT screenings; after the mailing the number rose to 25 (34%). The one-time cost to recruit each provider was less than the estimated annual cost savings associated with each child in the EPSDT program.

Warned, but not well armed: preventing viral upper respiratory infections in households.

The purpose of this state-of-the-science review was to identify strategies and household-level interventions for public health nurses to help prevent the acquisition and spread of viral upper respiratory infections (URI) in the community. Even though viral URI are a major global economic and social problem, surprisingly little research has been conducted to attempt to prevent them or reduce their transmission, probably because URI (with the exception of epidemic influenza) are generally considered to be mild and self-limited. Based on the research to date, public health nurses can use several promising strategies for prevention: (a) provide more tailored educational messages regarding preventive strategies such as vaccination, hand hygiene, spatial separation of infected household members, avoidance of antibiotics to treat viral URI, and environmental cleaning (e.g., for toys or other shared items), which are delivered personally rather than passively (e.g., pamphlets placed in a waiting room); (b) use each patient encounter in any setting to encourage influenza vaccination for relevant risk groups; (c) encourage use of alcohol hand sanitizers by household members during the cold and flu season; and (d) provide opportunities for skill development for adult and child household members (e.g., cover your cough, when to seek care or an antibiotic).

Access to nursing information resources.

There is a wealth of nursing information available in multiple formats (journal articles, books, audiovisuals, computer software, pamphlets, dissertations, etc.). But the resources are not readily available to help the nurse identify needed materials quickly and easily. Current access to nursing journal articles and books is evaluated in detail; the need to collect and organize other types of nursing information is outlined. Better control of nursing information is a must if nurses are to take their place alongside other health care professionals.

Infant car seat usage. Effectiveness of a postpartum educational program.

A study, based on the social learning theory model and designed to assess the effect of a postpartum educational program on mothers' use of infant car seats at the time of discharge was conducted. The control group consisted of data for 92 mothers obtained by recording their behavior at the time of discharge regarding their use of infant car seats and eight other related measures. The postpartum study group (90) was shown an educational slide/audio tape presentation followed by a question-and-answer period and demonstration of car seats. They were also given a shoppers' guide and a pamphlet of facts and pictures of car seats. Statistical significance was obtained on several measures.

Performing subcutaneous injections: a literature review.

BACKGROUND: Persons using daily subcutaneous injections to administer medicine perform them in different ways and thereby increase the risk of skin complications related to the injection. It is often part of nurses' role to administer medicine and educate the patient in injection technique. Course literature in nursing education, commercial patient education pamphlets, and instructional leaflets do not give consistent advice regarding subcutaneous injection technique. AIM: The aim of this review was to identify the scientific foundation for the technical performance of subcutaneous injections. The question to be answered was: How should a subcutaneous injection be administered to achieve the right dose in the right place with minimum complications? METHOD: The review included a search in three databases, a screening process at abstract level, followed by a quality assessment of included articles. The quality assessment was done independently by two people and followed specific protocols. RESULT: A total of 38 articles were assessed for quality and covered information on dose, location, and complications of subcutaneous injection. The assessed studies are heterogeneous in design and describe different aspects of the subcutaneous injection technique. Therefore, the scientific foundation for technical performance is weak. However, several studies indicate that the amount of subcutaneous fat and appropriate needle length are of high importance for the drug to reach the target tissue. CONCLUSION: More research regarding effective subcutaneous injection technique needs to be done.

Fetal alcohol spectrum disorders prevention: an exploratory study of women's use of, attitudes toward, and knowledge about alcohol.

PURPOSE: The incidence of fetal alcohol spectrum disorders (FASD) is increasing, even though it is 100% preventable. This study examined use of, knowledge about, and attitudes toward alcohol of women requesting emergency contraception (EC) and/or a pregnancy test, and evaluated whether a brief intervention would be effective in educating them about the risks of FASD. DATA SOURCES: Fifty women from two outpatient clinics participated. Information was collected on demographic and personal health habits, alcohol use, and knowledge of and attitudes toward alcohol. As a brief intervention to increase knowledge about FASD, participants read a short pamphlet about the risks of alcohol exposure in pregnancy and then completed a post-test questionnaire. Descriptive statistics, including means, standard deviations, and skewness, were calculated for all variables. Pearson correlations were computed to assess relationships between demographic/lifestyle variables and attitudes toward and knowledge about alcohol. Paired t-tests were used to analyze the relationship between pretest and post-test knowledge scores. CONCLUSIONS: The majority of participants were single (76%), college educated (94%), and received EC at the clinic visit (60%). The average age was 24 years. Slightly over half (52%) reported drinking beer at least once a week, with one to six cans on occasion. Younger women expressed more tolerant attitudes toward alcohol use (p= .02) and drank significantly more beer on occasion (p= .015). Women who reported drinking alcohol when they last had sex were significantly (p= .017) less tolerant in their attitudes toward alcohol use. The intervention used in this study was effective in communicating knowledge about FASD to this population (p < .0001). IMPLICATIONS FOR PRACTICE: These findings suggest that young women may be engaging in behaviors that could put potential offspring at risk for exposure to alcohol. Clinicians are advised to take a thorough history to determine alcohol use in all women of childbearing age and to provide information regarding FASD prevention.

The ASHA national HIV education needs assessment of health and education professionals.

The self-reported HIV education needs of teachers, PTA presidents, school administrators, school nurses, school board members, school counselors, and physicians (N = 2,855) were investigated. Resources, policy, training, and knowledge needs were assessed. Greatest reported needs for HIV resources included books, pamphlets, journal articles, films, and videos. More than half the respondents needed information on how to promote school health education programs as well as information on how to coordinate school-based HIV education programs with community, health, religious, and youth agencies. Respondents also indicated a need for model HIV policies on confidentiality, grade level appropriate HIV education, attendance for infected staff and students, and handling blood or body fluids. Training needs included updates on homosexuality and bisexuality, sexually transmitted diseases, risk behaviors for HIV transmission, intravenous drug use, death and dying, safer sex practices, and communicating about HIV with a sexual partner. Knowledge about HIV generally was high, but gaps were apparent regarding effects of HIV on the brain, transmission issues, prevention practices, and HIV antibody testing. Eighty-seven percent believed school-based health education is effective in preventing the spread of HIV. Respondents felt primary responsibility for conducting HIV education should rest with teachers (36%), parents (27%), and school nurses (26%).

Evaluating the impact of a promotional campaign for screening mammography: women's knowledge and sources of awareness.

The Breast X-Ray Programme of the Central Sydney Health Service was advertised by generalised strategies aimed at the total community, including poster and pamphlet distribution, and strategies aimed at general practitioners, supplemented by written invitations and recommendation from the general practitioner, invitations for friends, and invitations from the service using the electoral listing. In order to evaluate the reach or impact of the promotional campaign in the Drummoyne local government area, telephone interviews were conducted with women aged 45 to 70 randomly selected from the community. Women's knowledge about breast cancer, screening and the Breast X-Ray Programme, plus sociodemographic characteristics, were obtained before screening (n = 628), 10 months (n = 93) and 2 years after screening started (n = 206). While knowledge about risk did not change, significant increases were found in the proportion of women who had heard of mammography, screening mammography specifically and the screening van. In addition there were significant increases in the proportion of women exposed to information about screening mammograms. The campaign generally had an equal effect on different sociodemographic but managed to achieve greater effects in women of non-English-speaking backgrounds and lower occupational status. A random sample of program attenders aged 45 to 70 (n = 763) were asked how they found out about the van. 'Seeing the van' was the most consistently reported source of awareness. Others included 'GPs' 'newspapers', 'other print media' and 'personal networks'. Women with additional qualifications since leaving school were more likely to state 'newspaper' and 'other print media' as a source.

Radiation dose estimate in small animal SPECT and PET.

Calculations of radiation dose are important in assessing the medical and biological implications of ionizing radiation in medical imaging techniques such as SPECT and PET. In contrast, radiation dose estimates of SPECT and PET imaging of small animals are not very well established. For that reason we have estimated the whole-body radiation dose to mice and rats for isotopes such as 18F, 99mTc, 201Tl, (111)In, 123I, and 125I that are used commonly for small animal imaging. We have approximated mouse and rat bodies with uniform soft tissue equivalent ellipsoids. The mouse and rat sized ellipsoids had a mass of 30 g and 300 g, respectively, and a ratio of the principal axes of 1:1:4 and 0.7:1:4. The absorbed fractions for various photon energies have been calculated using the Monte Carlo software package MCNP. Using these values, we then calculated MIRD S-values for two geometries that model the distribution of activity in the animal body: (a) a central point source and (b) a homogeneously distributed source, and compared these values against S-value calculations for small ellipsoids tabulated in MIRD Pamphlet 8 to validate our results. Finally we calculated the radiation dose taking into account the biological half-life of the radiopharmaceuticals and the amount of activity administered. Our calculations produced S-values between 1.06 x 10(-13) Gy/Bq s and 2.77 x 10(-13) Gy/Bq s for SPECT agents, and 15.0 x 10(-13) Gy/Bq s for the PET agent 18F, assuming mouse sized ellipsoids with uniform source distribution. The S-values for a central point source in an ellipsoid are about 10% higher than the values obtained for the uniform source distribution. Furthermore, the S-values for mouse sized ellipsoids are approximately 10 times higher than for the rat sized ellipsoids reflecting the difference in mass. We reviewed published data to obtain administered radioactivity and residence times for small animal imaging. From these values and our computed S-values we estimated that the whole body dose in small animals ranges between 6 cGy and 90 cGy for mice and between about 1 cGy and 27 cGy for rats. The whole body dose in small animal imaging can be very high in comparison to the lethal dose to mice (LD50/30 approximately 7 Gy). For this reason the dose in small animal imaging should be monitored carefully and the administered activity should be kept to a minimum. These results also underscore the need of further development of instrumentation that improves detection efficiency and reduces radiation dose in small animal imaging.

A stylized computational model of the head for the reference Japanese male.

Computational models of human anatomy, along with Monte Carlo radiation transport simulations, have been used by Snyder et al. [MIRD Pamphlet No. 5, revised (The Society of Nuclear Medicine, New York, 1978)], Cristy and Eckerman [ORNL/TM-8381/VI, Oak Ridge National Laboratory, Oak Ridge, TN (1987)] and Zubal et al. [Med. Phys. 21, 299-302 (1994)] to estimate internal organ doses from internal and external radiation sources. These were created using physiological data from Caucasoid subjects but not from other races. There is a need for research to determine whether the obvious differences from the Caucasoid anatomy make these models unsuitable for estimating the absorbed dose in other races such as the Mongoloid. We used the cranial region of the adult Japanese male to represent the Mongoloid race. This region contains organs that are highly sensitive to radiation. The cranial region of a physical phantom produced by KYOTO KAGAKU Co., LTD. using numerical data from a Japanese Reference Man [Tanaka, Nippon Acta. Radiol. 48, 509-513 (1988)] was used to supply the data for the geometry of a stylized computational model. Our computational model was constructed with equations rather than voxel-based, in order to deal with as small a number of parameters as possible in the computer simulation experiment. The accuracy of our computational model was checked by comparing simulated experimental results obtained with MCNP4C with actual doses measured with thermoluminescence dosimeters (TLDs) inside the physical phantom from which our computational model was constructed. The TLDs, whose margin of error is less than +/-10%, were arranged at six positions. Co-60 was used as the radiation source. The irradiated dose was 2 Gy in terms of air kerma. In the computer simulation experiments, we used our computational model and Cristy's computational model, whose component data are those of the tissue substitute materials and of the human body as published in ICRU Report 46. The observed absorbed dose values (Gy) at all six points were calculated as the percentage difference between MCNP4C simulation and the TLDs. In our computational model, the average values of all the percentage differences were 6.0+/-4.0% (tissue substitute materials) and 7.6+/-6.6% (ICRU Report 46), respectively. In Cristy's model, the corresponding values were 20.4+/-3.8% (tissue substitute materials) and 21.0+/-4.1% (ICRU Report 46), respectively. Considering the margin of error in the radiation sensitivity of the TLDs, this study validates our computational model as a test object for radiation dosimetry studies.

A Monte Carlo approach to patient-specific dosimetry.

In internal emitter therapy, an accurate description of the absorbed dose distribution is necessary to establish an administered dose-response relationship, as well as to avoid critical organ toxicity. Given a spatial distribution of cumulated activity, an absorbed dose distribution that accounts for the effects of attenuation and scatter can be obtained using a Monte Carlo method that simulates particle transport across the various densities and atomic numbers encountered in the human body. Patient-specific information can be obtained from CT and SPECT or PET imaging. Since the data from these imaging modalities is discrete, it is necessary to develop a technique to efficiently transport particles across discrete media. The Monte Carlo-based algorithm presented in this article produces accurate absorbed dose distributions due to patient-specific density and radionuclide activity distributions. The method was verified by creating CT and SPECT arrays for the Medical Internal Radionuclide Dose (MIRD) Committee's Standard Man phantom, and reproducing the spatially averaged specific absorbed fractions reported in MIRD Pamphlet 5. The algorithm was used to investigate the implications of replacing a mean absorbed dose with a distribution, and of neglecting atomic number and density variations for various patient geometries and energies. For example, the I-131 specific absorbed fraction for spleen to liver is the same as for liver to spleen, yet the distributions were different. Furthermore, neglecting atomic number variations across the vertebral bone led to an overestimation of I-125 absorbed dose by an order of magnitude, while no error was observed for I-131.

Mutiny over Bounty?

Bounty Services Ltd advertise commercial products on postnatal wards of hospitals throughout Britain by means of free gifts. Since the " Bounty lady" is apparently well known to nursing staff but may have gone unnoticed by paediatricians and obstetricians an investigation was conducted of the quality of the gifts and the nature of the company. With two exceptions the samples and promotional leaflets were sound, and mothers apparently enjoyed receiving them. Educational pamphlets distributed with the gifts were excellent, and cine films shown to the mothers were of good quality and informative about basic parental skills. Bounty , however, operates by exerting commercial pressure on new mothers at a time when they are most vulnerable and distributes materials among them without consultation with medical staff. Most of the mothers questioned assumed that the service was being provided by the NHS. The Bounty service may or may not be perceived as a satisfactory operation but details should be known to paediatricians and obstetricians; any action to be taken might be decided locally after discussion in individual hospitals or districts.

The effectiveness of two smoking cessation programmes for use in general practice: a randomised clinical trial.

OBJECTIVE: To evaluate a structured, behavioural change, smoking cessation intervention designed for use within general practice. DESIGN: Randomised controlled clinical trial. SETTING: General practices in Newcastle, Australia. PATIENTS: 311 Patients identified as smokers by a screening question were enrolled in the study. Of these, 101 were assigned to a structured behavioural change programme, 104 to a simple advice programme adapted from previous research, and 106 to a control group. No significant differences were found between groups for demographic and smoking related variables before the study. INTERVENTIONS: Patients in the simple advice group received a brief statement of advice from the general practitioner as well as three pamphlets; those in the structured intervention group were given strategies which included attitude and behavioural change programmes as well as techniques to aid compliance. The amount of smoking in all groups was assessed by self reports with validation by measurement of salivary cotinine concentrations. MAIN OUTCOME MEASURE: Significant increase in cessation rates. CONCLUSIONS: Significant differences between controls and the structured behavioural change group were found at the one month follow up, but only for self reported abstinence. The simple advice programme did not produce any significant differences over the control group. General practitioner evaluation of the structured programme highlighted difficulties in relation to the duration of the intervention. Overall the structured programme in its present form did not appear to be an effective programme for use within general practice.

Effectiveness of a nicotine patch in helping people stop smoking: results of a randomised trial in general practice. Imperial Cancer Research Fund General Practice Research Group.

OBJECTIVE: To assess the effectiveness of 12 weeks' treatment with a 24 hour transdermal nicotine patch in helping heavy smokers to stop smoking; also to assess the value of a specially written support booklet about smoking cessation and patch use compared with a simple advice pamphlet. DESIGN: Double blind placebo controlled randomised trial with a 2 x 2 factorial design. SETTING: 19 general practices in Oxfordshire. SUBJECTS: 1686 heavy smokers aged 25-64 (mean cigarette consumption 24/day; mean duration of smoking 25 years). MAIN OUTCOME MEASURE: Sustained cessation for the last four weeks of the 12 week treatment period, confirmed by saliva cotinine estimation (226/262 cases; 86.3%) or expired carbon monoxide concentration (36/262; 13.7%). Patients lost to follow up (155/1686; 9%) were assumed to have continued to smoke. RESULTS: Cessation was confirmed in 163 patients (19.4%) using the nicotine patch and 99 patients (11.7%) using the placebo patch (difference 7.6% (95% confidence interval 4.2% to 11.1%); p < 0.0001). There was no significant advantage in using the more detailed written support material. The most important adverse effect of the patch was local skin irritation, which occurred in 15.8% (133/842) and 5.1% (43/844) of patients using the nicotine and placebo patches respectively, was graded as severe in 4.8% (40) and 1.1% (nine), and was stated as a reason for withdrawal from the trial in 9.5% (80) and 2.8% (24). CONCLUSION: Nicotine patches are effective in a general practice setting with nursing support, but the extent to which this effect is sustained cannot be assessed until the results of longer term follow up are known.

WHO at country level--a little impact, no strategy.

The acid test of WHO's effect on the world's health is its impact at country level. Unless it has an impact there, all of its declarations, its debates at the World Health Assembly, its conferences, its pamphlets, its political manouvering in Geneva and the regions, all of these come to nothing. Working as it does through national governments, WHO insists that it has no role in directly managing or delivering health care. Judging WHO's impact in individual countries is therefore difficult--its approaches are largely indirect, and initiatives may take years to bear fruit. But from the meagre resources that WHO makes available at country level it is clear why its country operations are criticised as the weakest link in an already weak chain of influence from its headquarters in Geneva to the people in its member states. Poorly funded, undertrained, and with no clear strategy to follow, its staff at country level stand little chance of making an impact.

Evaluation of Safe Kids Week 2004: age 4 to 9? It's booster seat time!

OBJECTIVE: To assess the effectiveness of a national one week media campaign promoting booster seat use. DESIGN: Pre-test, post-test design based on nationally representative random digit dialing telephone survey, with control for exposure to campaign. SETTING: Canada. SUBJECTS: Parents of children aged 4-9 years. INTERVENTIONS: During a one week campaign in May 2004, information on booster seat use was distributed via a national media campaign, retail stores, medical clinics, and community events. Information included pamphlets with guidelines for booster seat use, as well as a growth chart (designed by Safe Kids Canada) to assist parents in determining if their child should be using a booster seat. Assessing seat belt fit was described in detail on the growth chart. MAIN OUTCOME MEASURES: Knowledge, attitudes, and self-reported behaviors regarding booster seat use. RESULTS: Respondents in the group exposed to the campaign were twice as likely to report using a booster seat with lap and shoulder belt for their child (47%), compared to those in the pre-test (24%) and the unexposed (23%) groups (p<0.001). However, only small differences in general knowledge regarding booster seat use were found between the groups. CONCLUSIONS: A one week national media campaign substantially increased self-reported use of booster seats. Parents did not remember details of the campaign content, but did remember implications for their own child.
