Abstract
A critical shortage of trained cancer specialists is one of the major challenges in addressing the increasing cancer burden in low- and middle-income countries. Inadequate undergraduate cancer education in oncology remains a major obstacle for both task shifting to general practitioners and for training of specialists. We provide the first report of cancer education in Rwanda's undergraduate program to survey how new graduates are prepared to provide care for cancer patients. Anonymous online survey was sent January to June 2017 to medical students in their senior clinical years (years 5 and 6). Questions related to the demographics, medical curriculum, and general oncology exposure were included in the survey. Of 192 eligible students, 42% (n = 80) completed the survey and were analyzed. The majority were 25 to 29 years of age and 41% were female. Internal medicine was cited to provide the most exposure to cancer patients (50%) and cancer bedside teaching (55%). Close to a half (46%) have been taught oncology formally in addition to bedside teaching. A tenth (11%) of the participants felt comfortable in attending a cancer patient, and a fifth (21%) of the students felt comfortable while addressing multimodality treatment approach. The majority (99%) of the participants preferred having a formal oncology rotation. Of particular interest, 61% of the students are interested in pursuing an oncology career path. There is a need to modify the current oncology undergraduate curriculum to prepare future physicians for delivering cancer care in Rwanda. Raising the profile of oncology in undergraduate medical education will complement the on-going efforts to increase the country's capacity in task shifting and in training of cancer specialists.

Abstract
Abstract
Objective
In the context of sports-related concussion (SRC) evaluations, athletes have been shown to “sandbag” their baseline testing in order to improve their chances of return-to-play post-concussion. To circumvent this problem, performance validity tests are often administered. The ImPACT, a widely used computerized program in SRC evaluations, has five embedded validity indices (VIs); however, indications of their use as measures of effort have not been well established. With this in mind, we aimed to compare performance on the ImPACT VIs between athletes and non-athlete controls at baseline. Given the incentive to “sandbag” by at least some players, it was hypothesized that athletes would demonstrate poorer performance on all VIs than controls.
Method
Participants included 1,254 college students (70% male; 77.3% Caucasian) divided into two groups: athletes (n = 929) and non-athlete controls (n = 325). All participants completed the ImPACT individually. Primary outcomes of interest included the five ImPACT VIs: Impulse Control Composite, X’s and O’s Total Incorrect, Word Memory Learning Percent Correct, Design Memory Learning Percent Correct, and Three Letters Total Letters Correct.
Results
Independent samples t-tests revealed that athletes performed worse than controls on 4 of the 5 VIs (p = < .001 to .028; d = 0.13 to 0.23). The only VI that was not significantly different between groups was Three Letters (p>.05, d = 0.11).
Conclusion
Consistent with our hypotheses, findings generally showed that athletes demonstrated worse performance on the ImPACT VIs compared to non-athlete controls. Although future research is needed to validate the utility of the VIs, our results suggest that these scores may be useful in detecting suboptimal baseline performance.

Abstract
Background: In Haiti, cancer is associated with myths that have traumatic effects on patients and families. Cancer diagnoses are drivers of socioeconomic change, with psychological repercussions for an impoverished population. Aware of this reality, the Oncology Service at University Hospital of Mirebalais (HUM) created a dedicated psychosocial team, composed of a social worker, her assistant and a psychologist. Care is provided to patients and families through: individual counseling, support groups, outreach activities, home visits, and mental health consults. This abstract focuses on patient support groups (SG). SGs act as vectors of information and training that are capable of breaking myths, and accompanying patients on their cancer journey. Aim: The primary aim of SGs is to create a space for patients to participate in education and peer counseling. During sessions, the team encourages expressions of emotions and experiences in relation to the disease and its repercussions on patients and caregivers. These discussions encourage participant solidarity and strengthen compliance to treatments. SGs, however, are not static and services are continuously improved by collecting feedback. Methods: To address the psychosocial needs of each cancer patient, SGs were developed with specificity. Patients are categorized in SGs according to the medical treatment they are receiving. Other SGs offered, focus on caregiver experience. SGs have about 12 participants, last 120 minutes and are held in a private space in HUM. In general, discussions relate to patient experience, side effects, relationship implications, and socio-economic impacts. Across all SGs, principles for speaking are negotiated and are always at discretion of participants. Results: The HUM team has provided SG services since 2013. SGs are held often and the majority of oncology patients participate. In 2017, we held 30 SGs with over 380 participants. Therapeutic alliances have improved relationships: patient–patient, family–patient, and patient-clinician - fostering interdisciplinary collaboration. However, all SGs must be performed the same day as the medical appointment due to socio-economic difficulties that can create logistical challenges. Patient needs are also fluid and flexibility is key as SGs evolve. Conclusion: SGs play a critical role in comprehensive cancer care, particularly in Haiti where there are severe social implications for patients. Mental health of cancer patients is critical and SGs are an impactful way to address this need. Arranging SGs by medical treatment, the model used at HUM, is adaptable to other low-income settings. Every SG is different and facilitators approach each session without preconceptions, yet diligent to gather feedback. SGs provide critical information to clinicians about social determinants and implications of cancer diagnoses in Haiti. In the future, we hope to do robust qualitative analysis of SGs, using feedback from cancer patients at HUM.

Abstract
Background: Over 80% of children diagnosed with cancer survive in high-income countries (HICs). While the survival rate remains poor in low- and middle-income countries (LMICs) such as Rwanda, a growing number of children with cancer are surviving to adulthood. These children and young adults will face an increased risk of secondary cancers and late complications from their curative treatment. Cancer centers in HICs have established Long Term Survivorship (LTS) programs to cater for childhood cancer survivors and to capture these complications and/or recurrences at an early stage. They also address the more complex psychological and social aspects of surviving cancer in childhood. Aims: To develop an LTS program in Rwanda, initial training will take place in Botswana where a pediatric hematology-oncology (PHO) program was established at the national referral hospital, Princess Marina Hospital (PMH), in 2007. This training program will allow successful methods and lessons learned from the development of an LTS program in Botswana to establish a similar program in Rwanda with ongoing bidirectional collaboration. Methods: The Texas Children's Cancer and Hematology Centers (TXCH) Global Hematology-Oncology Pediatric Excellence (HOPE) program in Botswana is the only provider of PHO care in the country, provided at PMH, through a partnership with the Botswana government. The program has over 130 childhood cancer survivors in active follow-up. A one-month bench-marking visit will be conducted. During this period, Dr. Rubagumya will spend time with the medical director of the program learning how the LTS program was established and current operations. He will spend time with clinicians during consultations to understand the scope of tests requested, frequently asked questions across all parties: clinicians, survivors and/or caretakers and use of technology to aid in the management of LTS patients. Focused interviews of clinicians, patients, caregiver and administration will be conducted to further understand the challenges of the pediatric cancer survivors and the development of an LTS program in an LMIC face. Results: After this month visit, critical areas of knowledge transfer will include: how to set up a childhood cancer survivorship programs; methods for sustainable operation of a childhood cancer LTS program, and how to help childhood cancer survivors navigate health care systems. A similar model will be established in Rwanda. Long-term mentorship with Botswana colleagues will help to build Rwanda's first LTS. Conclusion: Survivors involved in dedicated LTS follow-up care have better health outcomes. This indicates the need for life long survivorship care. There is a dearth of data on how to establish and operate a childhood cancer LTS program in LMIC settings. Lessons learned through this program will guide us on how to set up such program in Rwanda.

Abstract
Background: Loss to follow-up after treatment initiation is a recognized and well-studied problem in cancer care programs in low- and low-middle income countries (LMIC). However, there is less literature on causes of treatment noninitiation in LMIC breast cancer programs. Hôpital Universitaire de Mirebalais (HUM) in Haiti established the main public comprehensive cancer center in the country in 2013. The facility is located in the Centre Department but serves patients from all the other nine departments (regions) of the country. Care provided within the facility is free after an initial nominal deposit, as a result of a multi-institutional collaboration with Zanmi Lasante, a local arm of Partners In Health, an international nonprofit organization, and US academic institutions. Aim: To determine the causes of treatment noninitiation and early loss to follow-up (LTFU) among a retrospective cohort of patients seen in the HUM breast cancer program. Methods: We evaluated 1371 women who had their first visit between July 1, 2013 and December 31, 2016. The list of breast cancer patients was generated from electronic medical record diagnosis codes. We identified individuals who were followed for less than 90 days (Under-90). We reviewed the patient's record to determine reason for care noninitiation and early losses. We used logistic regression analysis to determine if distance from HUM contributed to being Under-90, while controlling for demographic factors. Results: 339 (24.6%) patients in the breast cancer program were seen for less than 90-days. The two most common periods of early LTFU were prior to obtaining diagnostic biopsy (113 patients- 33%), and after referral for staging diagnostic imaging (83 patients- 24%). 49 patients (14%) had confirmed diagnosis and completed staging but never initiated treatment, while only 23 (7%) did not initiate treatment due to confirmed advanced metastatic disease or death. Majority of the patients 1254 (91.5%) came from outside the Centre region; early LTFU was more common among these patients (25.6%) compared with Centre region patients (16.2%). Using logistic regression analysis, controlling for age and rural/urban home classification, we found that the odds of Under-90 was 2.05 (95% CI: 1.22-3.45), P = 0.007, for those living outside the Centre region, compared with living in hospital's region. We repeated the analysis comparing the Centre region to the immediately adjacent regions, and more distant regions; we found the odds of Under-90 was 1.88 (95% CI: 1.12-3.18) for the adjacent regions, and 2.92 (95% CI: 1.61-5.31) for the distant regions. Conclusion: Treatment noninitiation and early losses are a significant problem in the HUM breast cancer program. As anticipated, living farther from HUM increased the odds of early LTFU. Effective interventions are needed to reduce the number of patients failing to initiate therapy, and these interventions must begin at the first contact with the oncology program.

Abstract
Background: Obesity and metabolic syndrome (MS) have been linked to increased risk of breast cancer recurrence and mortality in prospective cohorts. These studies have mostly occurred in high-income countries. Little is known about rates of obesity and what factors predict obesity in breast cancer patients from low- and low-middle income countries (LMIC). However, there are increasing rates of obesity in the general population of LMICs. Hôpital Universitaire de Mirebalais (HUM) in Haiti established the main public comprehensive cancer center in the country in 2013. The facility serves patients from all around the country. Aim: To establish the prevalence of obesity in a retrospective cohort of breast cancer patients at HUM, and evaluate the association between living in urban areas and obesity in this population. Methods: We evaluated 1035 women who had their first visit between July 1, 2013 and December 31, 2016, with a coded diagnosis of breast cancer, and who had been followed in the HUM program for ≥ 90 days. We abstracted their first recorded height, weight and blood pressure (BP). We identified individuals who met criteria for obesity (body mass index [BMI] ≥ 30 kg/m2), systolic hypertension (systolic BP [SBP] ≥ 135 mmHg), and diastolic hypertension (diastolic BP [DBP] ≥ 90 mmHg). After exclusion of missing data in the variables of interest, the final analysis cohort was 678. We classified home commune location as rural or urban based on World Bank and UN standards. We used logistic regression analysis to determine the odds of being obese for individuals living in urban areas compared with rural dwellers. Results: 179 breast cancer patients (26.4%) had BMI ≥ 30, of which 58 (8.5%) were morbidly obese (BMI ≥ 35). 309 (45.6%) patients had systolic hypertension (HTN) and 180 (26.6%) had diastolic HTN. 417 (61.5%) lived in urban areas; 125 (30%) of urban dwellers were obese while only 20.7% of rural dwellers were obese. The crude OR for obesity in urban versus rural areas was 1.64 (95% CI: 1.16-2.36). Using logistic regression analysis and controlling for age the OR for obesity in urban areas was 1.67 (95% CI: 1.15-2.40), P = 0.0162. We did a similar analysis for morbid obesity, while controlling for age, the OR in urban compared with rural patients was 2.16 (95% CI: 1.15-4.03), P = 0.0162. There were no statistically significant differences in SBP and DBP comparing rural and urban patients. Conclusion: HUM breast cancer patients from urban areas were more likely to be obese than rural dwellers. Urban patients were twice as likely to be morbidly obese. There were no differences in HTN between the groups. Higher rates of obesity in the HUM breast cancer population is partly driven by the higher proportion of urban patients. Further studies need to be done to evaluate the causes and mediators of obesity as well as its effect on patient cancer outcome in Haiti.

Abstract
Essential criteria for the methodological quality and validity of randomized controlled trials are the drop-out rates from both the experimental intervention and the study as a whole. This systematic review and meta-analysis assessed these drop-out rates in non-pharmacological schizophrenia trials. A systematic literature search was used to identify relevant trials with ≥100 sample size and to extract the drop-out data. The rates of drop-out from the experimental intervention and study were calculated with meta-analysis of proportions. Meta-regression was applied to explore the association between the study and sample characteristics and the drop-out rates. 43 RCTs were found, with drop-out from intervention ranging from 0% to 63% and study drop-out ranging from 4% to 71%. Meta-analyses of proportions showed an overall drop-out rate of 14% (95% CI: 13-15%) at the experimental intervention level and 20% (95% CI: 17-24%) at the study level. Meta-regression showed that the active intervention drop-out rates were predicted by the number of intervention sessions. In non-pharmacological schizophrenia trials, drop-out rates of less than 20% can be achieved for both the study and the experimental intervention. A high heterogeneity of drop-out rates across studies shows that even lower rates are achievable.

Abstract
Rabies remains a major neglected global zoonosis. New vaccine strategies are needed for human rabies prophylaxis. A single intramuscular immunization with a moderate dose of an experimental chimpanzee adenovirus (Ad) vector serotype SAd-V24, also termed AdC68, expressing the rabies virus glycoprotein, resulted in sustained titers of rabies virus neutralizing antibodies and protection against a lethal rabies virus challenge infection in a non-human primate model. Taken together, these data demonstrate the safety, immunogenicity, and efficacy of the recombinant Ad-rabies vector for further consideration in human clinical trials.

Abstract
Prey capture success and foraging mode were studied in brown trout Salmo trutta at temperatures ranging from 5.7 to 14.0° C. At low temperatures, there was a positive correlation between prey capture success and the proportion of time that the fish spent holding feeding stations. This correlation was not found at temperatures >10° C.

Abstract
The primitively social sweat bee, Lasioglossum zephyrum, blocks the entry into its nest of most conspecifics from other colonies. Laboratory inbreeding of these bees produced lines which showed a positive linear relationship between the coefficient of relationship of bees tested and how often they permitted non-nestmates to pass them. The most probable mechanism is a genetically determined odor coupled with a learned component by which guard bees discriminate between odors of close kin and other bees.

Abstract
BACKGROUND Trastuzumab-based adjuvant therapy has become the standard of care for human epidermal growth factor receptor-2 (HER2)-positive early breast cancer (EBC). Both anthracycline- and non-anthracycline-containing trastuzumab regimens are approved in the United States, but cardiotoxicity is increased with anthracycline-containing regimens. DESIGN This paper reviews published and reported efficacy and cardiac safety data from the adjuvant trastuzumab trials [National Surgical Adjuvant Breast and Bowel Project (NSABP) B-31/North Central Cancer Treatment Group (NCCTG) N9831, Breast Cancer International Research Group (BCIRG) 006, Herceptin Adjuvant (HERA), FinHer, and Programme Adjuvant Cancer Sein (PACS) 04]. RESULTS The addition of trastuzumab to adjuvant chemotherapy significantly improved disease-free survival (from 24% to 58%) in five of the six trials. Overall survival was significantly improved (23%-35%) in the large trials. In NSABP B-31/ NCCTG N9831, 5.0%-6.6% of patients who received doxorubicin and cyclophosphamide (AC) were unable to receive trastuzumab. Cardiac event rate was highest in the anthracycline-containing trastuzumab arms (1.9%-3.8%) and lowest with the regimen of docetaxel, carboplatin, and trastuzumab (TCH) (0.4%). CONCLUSIONS Incorporation of trastuzumab into anthracycline and non-anthracycline adjuvant chemotherapy regimens has substantially improved outcomes in HER2-postive EBC. The TCH regimen has the lowest rates of cardiac dysfunction, but uncertainty exists regarding the relative efficacy of TCH compared with anthracycline-containing trastuzumab regimens. Cardiac risk factor assessment can aid in selection of trastuzumab-based adjuvant therapy regimens.

Abstract
The Argentine ant, Linepithema humile (Mayr), and the red imported fire ant, Solenopsis invicta Buren, are natural agonists in their country of origin. Since the first report of L. humile in California in 1907 its range expanded statewide, displacing native ant species wherever it spread. Since the discovery of established populations of S. invicta in southern California in 1998, it has been restricted to discrete areas of southern California. However, as these discrete populations expand, they are encountering large populations of L. humile, which are effective competitors for available resources and are particularly aggressive in their encounters with other ant species such as S. invicta. Most Dolichoderine ants such as L. humile do not prefer to forage on baits made with defatted corn grit and soybean oil typically used in red imported fire ant control programs. Applications of these baits in areas where distributions of these species overlap might selectively affect populations of S. invicta and give L. humile a competitive advantage. Three laboratory experiments were conducted to determine the competitive outcomes between S. invicta pitted against L. humile: 1) agonistic behavior of workers in small arenas, 2) colony interactions with different population ratios, and 3) the effects of pyriproxyfen on the competitiveness of S. invicta against L. humile. Populations of S. invicta consisting of major workers killed more L. humile than did minors or a mixture of majors and minors. When paired against L. humile colonies consisting of 1,100 workers, colonies consisting of 38 S. invicta workers were easily defeated by L. humile. Colonies consisting of 450 S. invicta workers plugged their nest entrances, but they were ultimately defeated by L. humile after 13 d. The S. invicta colonies consisting of 1,100 workers took control of the bridge connecting the colonies, invaded the L. humile colony, killed the Argentine ant queens, and removed their brood. Pyriproxyfen-treated fire ant workers took significantly longer to chase the Argentine ants from a connecting bridge than did untreated fire ants. Thus, fire ant baits may have long-term effects on intercolonial aggression between S. invicta and L. humile, especially when Argentine ant populations are high in the summer.

Abstract
OBJECTIVES Health professionals play an integral role in assessing the risk of violence in their patients. However, there have been few evaluations of violence prevention education programs for health care personnel. The objective of this study was to evaluate the effects of a violence-screening education program on pediatric residents' and medical students' comfort level and skills in the identification and management of violence risks. SETTING Adolescent clinic of a tertiary care pediatric hospital. PARTICIPANTS Fifty-six second-year residents and third-year medical students assigned to a 4-week adolescent clinic rotation. DESIGN Randomized, controlled comparison study conducted over a 1-year period. INTERVENTION On alternate months, medical students and residents in the intervention group participated in a 3-hour workshop on violence prevention. The workshop included a didactic session with an overview of firearm, media, and sexual violence; a discussion of risk factors for adolescent violence; and training on the approach to the adolescent interview. Participants also discussed violence risks in the community with a panel of teen health educators, engaged in one-on-one role play with the youth educators, and received feedback on their violence screening skills. The control group received the standard ambulatory clinic manual with articles on violence prevention. EVALUATION METHODS All participants completed prerotation and postrotation questionnaires assessing their self-reported screening practices, as well as perceived importance and confidence in violence screening. Participants also interviewed and examined an adolescent standardized patient (SP) in the clinic. SPs completed evaluations on the content of the residents' and students' screening, their interpersonal skills, and their skill in the identification and management of the violence-related problem. RESULTS Over 12 months, 30 control and 26 intervention participants were recruited. There were no differences in prerotation questionnaire scores for intervention and control groups in screening practices, perceived importance and confidence in violence screening. Postrotation intervention participants reported more screening compared with controls on violence in school/neighborhood and fighting history. There was also greater perceived importance in asking about access/use of weapons and violence in school/neighborhood. Intervention participants also had improved performance compared with controls on SP evaluations of screening for violence, identification and management of the violence-related scenario, and interpersonal skills. CONCLUSION A violence prevention education program with teen health educators improved participants' self-reported violence questioning, as well as increased perceived comfort and importance in violence screening. Participants in the program also improved their identification and management of a standardized violence-related scenario presented in an adolescent clinic setting. adolescent violence, physician education, violence risk screening.

Abstract
OBJECTIVES At present, many clinical trials of anti-HIV-1 therapies compare treatments by a primary endpoint that measures the durability of suppression of HIV-1 replication. Several durability endpoints are compared. DESIGN Endpoints are compared by their implicit assumptions regarding surrogacy for clinical outcomes, sample size requirements, and accommodations for inter-patient differences in baseline plasma HIV-1-RNA levels and in initial treatment response. METHODS Virological failure is defined by the non-suppression of virus levels at a prespecified follow-up time T(early virological failure), or by relapse. A binary virological failure endpoint is compared with three time-to-virological failure endpoints: time from (i) randomization that assigns early failures a failure time of T weeks; (ii) randomization that extends the early failure time T for slowly responding subjects; and (iii) virological response that assigns non-responders a failure time of 0 weeks. Endpoint differences are illustrated with Agouron's trial 511. RESULTS In comparing high with low-dose nelfinavir (NFV) regimens in Agouron 511, the difference in Kaplan-Meier estimates of the proportion not failing by 24 weeks is 16.7% (P = 0.048), 6.5% (P = 0.29) and 22.9% (P = 0.0030) for endpoints (i), (ii) and (iii), respectively. The results differ because NFV suppresses virus more quickly at the higher dose, and the endpoints weigh this treatment difference differently. This illustrates that careful consideration needs to be given to choosing a primary endpoint that will detect treatment differences of interest. CONCLUSION A time from randomization endpoint is usually recommended because of its advantages in flexibility and sample size, especially at interim analyses, and for its interpretation for patient management.

Abstract
The oral toxicity of boron compounds to the Argentine ant, Linepithema humile (Mayr), was evaluated in laboratory tests. The ants were provided 25% sucrose water containing 0.5 and 1% boric acid, disodium octaborate tetrahydrate, and borax. Lethal times of these solutions were a function of the concentration of boron. In field tests, the ants showed no discrimination between disodium octaborate tetrahydrate and boric acid. There was a significant reduction in consumption of sucrose water with > 1% boric acid.

Abstract
Pediatrics has attempted to inculcate the "culture of prevention" into practice, both through anticipatory guidance in well-child care and through behavioral interventions in sick care. The effectivenesses of many components of well-child care have not been conclusively demonstrated, particularly in health education, counseling, and anticipatory guidance, nor has teaching prevention in pediatrics been thoroughly evaluated. This article reviews methods of teaching prevention in pediatrics and highlights innovative programs. Teaching programs use the wide range of approaches now common in medical education, in a variety of inpatient and outpatient sites. Programs across the country are trying new approaches to teaching traditional topics or are introducing new topics into their curricula. Examples of specific programs are given, organized by the themes of the programs. The field needs to develop in three major directions. First, there is a need to develop competencies and curricula in prevention issues of contemporary importance, including the new morbidities, cross-cultural issues, cost-effectiveness, quality of care, and practice in managed care and other community settings. Second, further work is needed to evaluate programs and measure educational outcomes. This feedback must in turn be used to redefine competencies, curricula, and programs, Third, there needs to be an accessible clearinghouse, and educational tools need to be disseminated. To be effective, a curriculum for prevention in pediatrics cannot stand alone, but must be part of a vertically and horizontally integrated curriculum. Further, creating horizontally and vertically integrated curricula in prevention teaching across disciplines should be the standard.

Abstract
We investigated whether the Argentine ant, Linepithema humile (Mayr), trail pheromone, Z9-16:Ald, could enhance recruitment to and consumption of liquid sucrose solutions. All tests were done as paired comparisons with a 10% sucrose solution as food. In the laboratory, mixing 20 microl of a 10-microg/ml solution of the pheromone with 50 microl of the 10% sucrose solution increased the number of ants feeding by >150%. In a field test, we combined the trail pheromone with a 10% sucrose solution in 50-ml vials. These vials were covered with a plastic membrane that has 1.5-mm-diameter holes punched uniformly across its surface. Ants could drink from the holes after the vials were inverted. For half of the vials, 1 microg of the pheromone was put onto the plastic membrane before the vials were filled with a 10% sucrose solution. The remaining vials had no pheromone on the plastic membrane. After 4 h we measured the consumption in each vial. Bait consumption with the pheromone was enhanced by 29%. In a 2nd series of tests, vials were left outside for 24 h. The consumption rate was 33% higher with the pheromone compared with the controls that didn't have pheromone.

Abstract
Augmentation of the calf for correction of contour deformities has been most frequently performed utilizing silicone implants. Results of such implants have often been unsatisfactory. We report the case of a 27-year-old woman who chose the use of a transverse rectus abdominis myocutaneous (TRAM) free flap for correction of a left calf contour deformity from childhood polio. This is the first report of calf augmentation with the use of a TRAM free flap and excellent results were obtained.

Abstract
BACKGROUND Patients with ESRD have excessive cardiovascular morbidity and mortality. In postmenopausal women with normal renal function, estrogen replacement therapy decreases cardiovascular mortality by 50%, in part because of their beneficial effects on the lipoprotein profile. Because of similarities in the lipoprotein profile between healthy, postmenopausal women, and women with ESRD, we examined the effects of estrogen replacement on lipoproteins in 11 postmenopausal women with ESRD. METHODS In a randomized, placebo-controlled crossover study (8 week treatment arms) using 2 mg daily of oral, micronized estradiol, 11 postmenopausal women with ESRD were treated. Neither baseline lipid nor lipoprotein abnormalities were used as entry criteria for study participation. RESULTS Blood estradiol levels were 19 +/- 4 with placebo and 194 +/- 67 pg/ml (P = 0.024) with estradiol treatment. Total HDL cholesterol concentrations increased from 52 +/- 19 mg/dl to 61 +/- 20 mg/dl (16%), with placebo and estradiol treatments, respectively (P = 0.002). Apolipoprotein A1 increased by 24.6% (P = 0.0002) with estradiol intervention. HDL2 concentrations were 19 +/- 13 with placebo and 24 +/- 16 with estradiol treatment (P = 0.046). There were no differences in total or LDL cholesterol, other lipoprotein fractions including Lp(a), and triglycerides with 2 mg daily estradiol treatment. No significant side effects were observed. CONCLUSIONS Therefore, using standard dosage regimens for estrogen replacement therapy in postmenopausal women with ESRD, HDL cholesterol is increased to an extent that would be expected to improve their cardiovascular risk profile. Further studies are needed to assess whether estrogen replacement therapy decreases the incidence or severity of cardiovascular disease in ESRD patients to a similar degree compared with other women.

Abstract
OBJECTIVE Under managed care, telephone management is crucial to pediatric practice, but an effective method is needed to teach residents telephone skills. Our objective was to design an interactive CD-ROM program to teach residents an organized, consistent approach to telephone complaints and to determine whether use of the program was associated with better subsequent telephone management than reading the same information. SETTING The general pediatric ambulatory center of a tertiary care children's hospital. PARTICIPANTS A total of 24 PL-2 and PL-3 pediatric residents. DESIGN A randomized, prospective, controlled comparison was conducted of resident management of two telephone calls: a 5-year-old with cough and trouble breathing, and a 7-year-old with fever. Thirteen residents were randomized to the computer group and 11 to the reading control group. Intervention. Scripts, scoring, and feedback for 10 CD-ROM-simulated calls were developed from texts and pediatrician survey using a modified Delphi technique. Volunteers acted out the caller's role in scenario scripts and were recorded onto a CD-ROM. The computer simulated calls by recognizing questions typed in a free-form format and answering with a voice response. Feedback was provided for omissions in history-taking and errors in assessment, triage, and home management. The computer group worked through the CD-ROM calls while the control group had equal time to read the same information. Evaluation Measures. A trained, standardized patient acted as the mother in pretest calls placed at the beginning of the month and posttest calls at the end. Calls were recorded and scored in a blinded manner using scoring templates and on interpersonal skills using the Patient Perception Questionnaire. RESULTS Pretest scores for the two calls were similar in the computer versus the control group (cough, 70.33% +/- 8.36 vs 68.46% +/- 6.73; fever, 75.64% +/- 9.82 vs 73.59% +/- 9.06). Posttest scores were significantly higher in the computer group than in the control group on both calls (cough, 79.08% +/- 8.17 vs 69 +/- 13.3; fever: 83.33% +/- 9.96 vs 70.35% +/- 9.66). Interpersonal skills also were similar pretest (19 +/- 3.4 vs 20 +/- 2.7). There was modest improvement in both groups without a statistically significant difference in posttest scores (24.2 +/- 2.9 vs 22.5 +/- 3.1). CONCLUSIONS Use of this CD-ROM telephone management program was associated with better postintervention telephone management. The program augments faculty instruction by teaching a consistent, general approach to telephone management.

Abstract
OBJECTIVE The Health Resources and Services Administration's Bureau of Health Professions developed a demographic utilization-based model of physician specialty requirements to explore the consequences of a broad range of scenarios pertaining to the nation's health care delivery system on need for physicians. DATA SOURCE/STUDY SETTING The model uses selected data primarily from the National Center for Health Statistics, the American Medical Association, and the U.S. Bureau of Census. Forecasts are national estimates. STUDY DESIGN Current (1989) utilization rates for ambulatory and inpatient medical specialty services were obtained for the population according to age, gender, race/ethnicity, and insurance status. These rates are used to estimate specialty-specific total service utilization expressed in patient care minutes for future populations and converted to physician requirements by applying per-physician productivity estimates. DATA COLLECTION/EXTRACTION METHODS Secondary data were analyzed and put into matrixes for use in the mainframe computer-based model. Several missing data points, e.g., for HMO-enrolled populations, were extrapolated from available data by the project's contractor. PRINCIPAL FINDINGS The authors contend that the Bureau's demographic utilization model represents improvements over other data-driven methodologies that rely on staffing ratios and similar supply-determined bases for estimating requirements. The model's distinct utility rests in offering national-level physician specialty requirements forecasts.

Abstract
OBJECTIVE To assess the prevalence of use of anabolic-androgenic steroids and other presumed performance-enhancing drugs and the associated knowledge, attitudes, and behavior of school-aged Canadians. DESIGN A national survey was conducted using a self-report questionnaire distributed randomly to schools within each of five Canadian regions. SETTING Canada. SUBJECTS The subjects were 16,119 Canadian students, in the sixth grade and above, from 107 schools drawn randomly from five Canadian regions. MAIN OUTCOME MEASUREMENTS The number of students reporting the use of anabolic-androgenic steroids and other performance-enhancing drugs in the year before the survey, the nature of such drug-taking activities, and the attitudes underlying the decision to take anabolic-androgenic steroids. RESULTS More than 83,000 young Canadians (2.8% of the respondents) are estimated to have used anabolic-androgenic steroids in the year before the survey. Of those taking such drugs, 29.4% reported that they injected them; of the latter group, 29.2% reported sharing needles in the course of injecting anabolic-androgenic steroids. Significant numbers of respondents reported using other substances (caffeine, 27%; extra protein, 27%; alcohol, 8.6%; painkillers, 9%; stimulants, 3.1%; "doping methods," 2.3%; beta-blockers, 1%) in attempts to improve sport performance. CONCLUSIONS The use of anabolic-androgenic steroids is more widespread than may have been assumed and is often accompanied by high-risk needle-sharing. Anabolic-androgenic steroid use is often intended to alter body build as opposed to accentuating sport performance. Many young Canadians use a variety of other substances in attempts to improve sport performance. Drug-taking of this kind represents a special challenge for educators, health professionals, and sport authorities.

Abstract
OBJECTIVE A national health objective for the year 2000 is that at least 90% of hospital emergency departments have protocols for routine identification, treatment, and referral for victims of spouse abuse. An effective assessment tool is needed to implement such protocols. METHODS To test the effectiveness of a two-question, nurse-administered, screening tool to detect physical abuse, 416 black, Hispanic, and white women coming to public and private emergency departments with vaginal bleeding were asked two questions. Additionally, a 14-item Danger Assessment Scale to determine risk factors of homicide was administered to all women. RESULTS In response to the two-question abuse assessment screen, 38% of the 416 women reported a history of physical or sexual abuse. For 61% of the women, the last episode of abuse occurred within the last 12 months. White women reported significantly more abuse than other ethnic groups (chi 2 = 18.71; df = 2; p = 0.00009). Teenagers reported more risk factors of homicide. DISCUSSION Abuse to women who seek care in emergency departments is common and easily detected with a straightforward two-question screen. Universal assessment and accompanying information on safety and community resources is essential to interrupt abuse, prevent further trauma and potential homicide, and promote the health and safety of women.

Abstract
Since the advent of the clerkship at The Johns Hopkins Medical School in the late 19th century, this model has been the backbone of clinical training for medical students throughout the world. Despite the pervasiveness of clerkships, little information exists about the faculty that oversees them administratively. We documented the reported academic credentials, professional development, and support systems for pediatric clerkship directors in the United States and Canada. Our findings should be useful to clerkship directors and department chairpersons across disciplines.
