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
This special issue of Medical Care Research and Review features articles developed for a national conference on performance measurement in preferred provider organizations (PPOs). The conference, “PPO Performance Measurement: Agenda for the Future,” was held March 15-16, 2001, in Washington, D.C.

Abstract
This special issue of Medical Care Research and Review features articles developed for a national conference on performance measurement in preferred provider organizations (PPOs). The conference, “PPO Performance Measurement: Agenda for the Future,” was held March 15-16, 2001, in Washington, D.C. It brought together various stake-holders—industry representatives, consumers, purchasers, and regulators—to discuss the state of PPO performance reporting and develop a strategy for future directions. These articles provided the background for an informed dialogue. The American Accreditation HealthCare Commission (URAC), the Consumer Coalition for Quality HealthCare, the Joint Commission on Accreditation of Healthcare Organizations, and the National Committee for Quality Assurance cosponsored the conference with a grant from the Agency for Healthcare Research and Quality to URAC.

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
PURPOSE/OBJECTIVES The Case Management Society of America (CMSA) developed evidence-based guidelines (Case Management Adherence Guidelines, CMAG) for case managers to support increased efficacy of case managers in helping patients become more adherent to medication regimens. The effort was in response to documented high levels of nonadherence, and evidence demonstrating that lack of adherence negatively impacts patient health status. The CMSA engaged in a massive training program to support case manager adoption of the CMAG tools and approaches to improve patient knowledge and motivation. This article reports on findings of a follow-up survey that evaluated case manager's use of the tools and strategies discussed in the CMAG. PRIMARY PRACTICE SETTING(S) Seven hundred fifty case managers from all settings were trained in the use of the CMAG. FINDINGS/CONCLUSIONS In a follow-up survey, 42% of respondents reported that there has been a very, or fairly, significant impact of using their new skills to increase their effectiveness in helping patients reach their outcome improvement goals. In addition, 43% reported that there has been a very, or fairly, big improvement in patient adherence since they took the training, while 39% did not see a major impact. At the time of the survey (up to 1 year after training), 43% of respondents indicated that the training was very valuable; another 39% reported that it was fairly valuable. Participants continue to use the skills and information adopted in the training sessions: 26% report that they currently use at least some of the information and skills very often, while another 49% use them fairly often. Sixty-six percent of respondents indicated that they specifically use motivational interviewing to help address patient knowledge and motivation regarding medication adherence. IMPLICATIONS FOR CASE MANAGEMENT PRACTICE Medication adherence is a key issue in case management practice; efforts to positively impact low patient knowledge and motivation can be frustration for case managers. The CMAG offer evidence-based assessment tools to evaluate patient knowledge of medications and their motivation to adhere, and recommend the strategy of motivational interviewing to help case managers address adherence more effectively with patients. A 1-time training on the CMAG and motivational interviewing had some effect on self-reported case manager effectiveness in addressing medication adherence. Case managers appreciated the training; many reported that they continue to use skills and that they have observed changes in patient outcomes. Additional training, skill building, and reinforcement may help case managers apply CMAG and motivational interviewing effectively to support patients' adherence to medication regimens. The CMSA may continue to evaluate the impact of the CMAG and CMAG training to refine the tools and the training approach.

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
BACKGROUND Health care queries rank among the most frequent topics of information-seeking activity initiated by users of commercial search engines. The quality of information located through existing search engine technology has received little attention, especially when considering the widely varied knowledge levels of internet users. OBJECTIVE This study sought to create a benchmark technology assessment of online health search trends and practices, with corresponding evaluation of its applicability within the Federal Health Architecture (FHA) plan for a nationwide, interoperable health information infrastructure. DESIGN Exploratory technology assessment, analyzing focus group participants' views on barriers to effective health information searching, using existing commercial search engine technologies and methods. SETTING AND PARTICIPANTS Focus group, national leaders in electronic health care (e-health). RESULTS A variety of web-based assessment tools are available for consumers to be able to identify reliable health websites; however, many may be too difficult for the layperson to use or understand. Existing search technologies are increasingly powerful, although the expanding volume of information on the internet suggests the need for better mediated searching. Search engines provide consumers a means for quickly bypassing information that appears too technical for their individual knowledge level, and at times, searchers often overlook critical information most relevant to their needs. Overall, existing search technologies need to be more interactive, visible, and context-driven, and supported by better technology assessment methodologies, scalability of information, and enhanced access by underserved subgroups. CONCLUSION Future technology assessments are needed to provide structure for interoperability of health information systems, especially where consumers, providers, and payer systems intersect. State-of-the-art search engine technologies are still not widely available to those who can benefit most from them.

Abstract
Patient safety is an important concern of many healthcare stakeholders, including patients, providers, employers, health plans, and insurers. In 2003, URAC conducted a qualitative study to examine the role of utilization management programs as part of a systemic approach to promoting patient safety. Many of URAC's findings are applicable to case management as well. URAC found that most medical management companies address patient safety indirectly, as part of a global quality management program. Even so, the study identified a number of strengths that could be deployed by medical management organizations to more systematically promote patient safety. For example, case management organizations use decision support tools to assist frontline practitioners in conducting assessments and tracking interventions. Such systems could be programmed to flag safety concerns and guide interventions. The study also found that commonly used case management assessment protocols could be adapted to routinely assess for high priority safety concerns. URAC concluded that each stage of the medical management process offers opportunities for data collection and clinical interface to promote patient safety. Case managers have key positions interfacing between patients, providers, and the healthcare system. Development of safety indicators and training of staff are key elements needed to effectuate a safety program in medical management. Case management leaders in each organization and at the national level should make patient safety a priority, and define the processes for implementing safety systems wherever case management is practiced.

Abstract
Background Searches for health information are among the most common reasons that consumers use the Internet. Both consumers and quality experts have raised concerns about the quality of information on the Web and the ability of consumers to find accurate information that meets their needs. Objective To produce a national stakeholder-driven agenda for research, technical improvements, and education that will improve the results of consumer searches for health information on the Internet. Methods URAC, a national accreditation organization, and Consumer WebWatch (CWW), a project of Consumers Union (a consumer advocacy organization), conducted a review of factors influencing the results of online health searches. The organizations convened two stakeholder groups of consumers, quality experts, search engine experts, researchers, health-care providers, informatics specialists, and others. Meeting participants reviewed existing information and developed recommendations for improving the results of online consumer searches for health information. Participants were not asked to vote on or endorse the recommendations. Our working definition of a quality Web site was one that contained accurate, reliable, and complete information. Results The Internet has greatly improved access to health information for consumers. There is great variation in how consumers seek information via the Internet, and in how successful they are in searching for health information. Further, there is variation among Web sites, both in quality and accessibility. Many Web site features affect the capability of search engines to find and index them. Conclusions Research is needed to define quality elements of Web sites that could be retrieved by search engines and understand how to meet the needs of different types of searchers. Technological research should seek to develop more sophisticated approaches for tagging information, and to develop searches that "learn" from consumer behavior. Finally, education initiatives are needed to help consumers search more effectively and to help them critically evaluate the information they find.

Abstract
URAC recently completed a study funded by the Robert Wood Johnson Foundation to assess patient safety systems. URAC collected information from 31 separate UM companies. URAC also reviewed software capabilities from four commercial utilization management software vendors. This article describes how utilization management organizations use information technology and UM processes to systematically identify and manage potential patient safety problems. The study also identified research needs to promote future utilization management involvement in patient safety.

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.
