Rapid neurodevelopmental recovery after ART initiation in an infant with HIV encephalopathy.

While there is ample evidence that antiretroviral therapy (ART) can improve cognitive outcomes in older children living with HIV, encephalopathy in infants has historically been considered an advanced disease presentation with less likelihood of neurodevelopmental recovery on treatment. More recent studies suggest that timely ART can halt encephalopathic disease progression and even lead to symptom resolution. Here we present a case of an HIV-positive infant diagnosed with encephalopathy who experienced impressive and rapid improvement with a multi-disciplinary care approach that included physical and occupational therapy and ART.

Video simulation to learn pediatric resuscitation skills tailored to a low resource setting: A pilot program in Iquitos, Peru.

INTRODUCTION: The Hospital Regional de Loreto in Peru partners with the University of California Los Angeles Global Health Program to enhance educational experiences for US and Peruvian trainees. University of California Los Angeles Pediatric faculty led intermittent in-person code simulation sessions for Peruvian residents, and there is a need for regular education on this topic. METHODS: University of California Los Angeles residents created a video simulation of a patient in respiratory distress. The video was presented to Hospital Regional de Loreto trainees in pediatrics. Stakeholder interviews and reuse of the video after initial presentation assessed acceptability of this mode of education by the site. Pre- and post-surveys using numerical rating scales evaluated the educational utility of this specific simulation video. Paired t-tests compared the pre- and post-surveys in the effectiveness of increasing the trainees' comfort of specific resuscitation skills. RESULTS: Stakeholder interviews revealed the video simulation was integrated into formal intern orientation trainings as well as used for resident and physician trainings multiple times in the year after the introduction. Twenty trainees completed the pre-intervention survey and 19 completed the post-intervention survey. Trainee comfort with code team leadership (2.6 ± 0.9, 3.5 ± 0.09, p = 0.03) and arrhythmia recognition/automated external defibrillator (AED) management (2.4 ± 0.9, 3.1 ± 0.9, p = 0.03) increased significantly with the video intervention. There was no significant difference in comfort with other skills. Overall, trainees rated the helpfulness of the video as an average of 4.2 (±1.1) out of 5. The most common positive feedback included the utility of reviewing medication dosing and the skill of performing chest compressions. The most common suggestions for improvement were to review more pathophysiology and simulate available resources at Hospital Regional de Loreto more realistically. CONCLUSION: E-learning is an acceptable mode of education in a resource-limited setting when tailored to the local context. This pilot project demonstrated short-term improvement in reported confidence and skills with some aspects of pediatric resuscitation.

Resiliency, Stress, and Culture Shock: Findings from a Global Health Service Partnership Educator Cohort.

Background: Global health field assignments for medical and nursing professionals include a wide variety of opportunities. Many placements often involve individuals practicing in settings very different from their home environments, relying on their professional experience to help bridge cultural and clinical divides. Objectives: There is limited information about the individual factors that might lead to successful longer-term global health experiences in non-disaster settings. In this paper, we report on one cohort of health professionals' experiences of culture shock, stress, and resiliency as volunteers within the Global Health Service Partnership (GHSP), a public-private collaboration between Seed Global Health, the US Peace Corps, and the US Presidents Plan for Emergency Aids Relief (PEPFAR) that placed American medical and nursing educators in five African countries facing a shortage of health professionals. Methods: Using the tools of Project PRIME (Psychosocial Response to International Medical Electives) as a basis, we created the GHSP Educator Support Survey to measure resiliency, stress, and culture shock levels in a cohort of GHSP volunteers during their year of service. Findings: In our sample, participants were likely to experience lower levels of resiliency during initial quarters of global health placements compared to later timepoints. However, they were likely to experience similar stress and culture shock levels across quarters. Levels of preparedness and resources available, and medical needs in the community where the volunteer was placed played a role in the levels of resiliency, stress, and culture shock reported throughout the year. Conclusion: The GHSP Educator Support Survey represented a novel attempt to evaluate the longitudinal mental well-being of medical and nursing volunteers engaged in intense, long-term global health placements in high acuity, low resource clinical and teaching settings. Our findings highlight the need for additional research in this critical area of global health.

Risk perception and beliefs regarding HIV infection among Ethiopian immigrants.

In Ethiopia, approximately 7.5% of the urban population is HIV-positive, and countrywide 1.5 million people are living with HIV. Between 1990 and 2000, immigration into the United States by African-born immigrants increased by 130%. Of this immigrant population, individuals from Ethiopia make up a significant portion. Although there is a rich literature addressing the beliefs regarding HIV and risk perception among some immigrant populations in the United States, few studies target Ethiopian-born residents. Thus, a survey-based study addressing demographics, acculturation, awareness, beliefs and risk perception, attitudes toward susceptibility for infection, and risk behaviors targeted Ethiopian-born residents of San Diego, California. Results indicate a separation between understanding of HIV transmission and personal risk perception for infection in a young, highly educated, predominantly male participant pool. As an initial study of HIV beliefs and risk perception in the immigrant Ethiopian population, our results provide information on specific areas warranting further investigation.

An equivalent illuminant model for the effect of surface slant on perceived lightness.

In the companion study (C. Ripamonti et al., 2004), we present data that measure the effect of surface slant on perceived lightness. Observers are neither perfectly lightness constant nor luminance matchers, and there is considerable individual variation in performance. This work develops a parametric model that accounts for how each observer's lightness matches vary as a function of surface slant. The model is derived from consideration of an inverse optics calculation that could achieve constancy. The inverse optics calculation begins with parameters that describe the illumination geometry. If these parameters match those of the physical scene, the calculation achieves constancy. Deviations in the model's parameters from those of the scene predict deviations from constancy. We used numerical search to fit the model to each observer's data. The model accounts for the diverse range of results seen in the experimental data in a unified manner, and examination of its parameters allows interpretation of the data that goes beyond what is possible with the raw data alone.
