Data management for large community trials in Nepal.

The current accessibility and sophistication of hardware and software has made it possible to design high-quality data management systems for community-based trials in resource-poor environments. We designed, implemented, and operated an effective data management system for the Nepal Nutrition Intervention Project Sarlahi (NNIPS), a placebo-controlled community trial to assess the impact of vitamin A supplementation on the preschool mortality of 38,000 children in the Sarlahi district of Nepal. A data center was established in Kathmandu, approximately 8 hr drive from the study area. The trial is now completed and over 200,000 forms have been processed. The majority of potential data discrepancies were identified and corrected by field workers during the interviews. Supervisors and forms editors located at the field office corrected most data errors. Once forms reach Kathmandu, the average number of data entry errors was 3.1 per 10,000 keystrokes for the eight data entry operators employed during the study. Extensive computerized checking of data during data entry found out-of-range, missing, or inconsistent data in only 1% of forms. Timely analysis of field worker performance provided ongoing feedback to supervisors and analysis for the Data Safety and Monitoring Committee, and for publication of results.

Restructuring the therapeutic environment to promote care and safety for the obese patient.

Fifty-four percent of American adults are overweight. Obesity is a chronic disease associated with a number of conditions, such as diabetes, heart disease, hypertension, certain types of cancers, and breathing problems. The direct and indirect costs related to obesity exceed $70 billion annually. Because of the many cost and quality issues related to obesity, national attention is turning toward the special needs of this population. Strategies to restructure therapeutic intervention with attention to risk management, economic implications, and patient satisfaction are important considerations when managing the obese patient.

From nightlife conventions to daytime hidden agendas: dynamics of urban sexual territories in the South of France.

This article focuses on the space-time dynamics of sexual encounters in city neighborhoods associated with sex work and cruising. The data were collected as part of a multisite, longitudinal ethnographic study conducted in major cities of southern France. The results suggest that there is a continuous interaction between these sexualized public spaces and urban planning. Urban planners, however, are not the only actors shaping the location and the use of the space. Participants create a dialectical movement from night normative worlds to occult practices interwoven with daytime activities. They also create subtle social rules governing actors and their practices.

Urbanization, urbanicity, and health.

A majority of the world's population will live in urban areas by 2007. The most rapidly urbanizing cities are in less-wealthy nations, and the pace of growth varies among regions. There are few data linking features of cities to the health of populations. We suggest a framework to guide inquiry into features of the urban environment that affect health and well-being. We consider two key dimensions: urbanization and urbanicity. Urbanization refers to change in size, density, and heterogeneity of cities. Urbanicity refers to the impact of living in urban areas at a given time. A review of the published literature suggests that most of the important factors that affect health can be considered within three broad themes: the social environment, the physical environment, and access to health and social services. The development of urban health as a discipline will need to draw on the strengths of diverse academic areas of study (e.g., ecology, epidemiology, sociology). Cross-national research may provide insights about the key features of cities and how urbanization influences population health.

Healthy places: exploring the evidence.

"Sense of place" is a widely discussed concept in fields as diverse as geography, environmental psychology, and art, but it has little traction in the field of public health. The health impact of place includes physical, psychological, social, spiritual, and aesthetic outcomes. In this article, the author introduces sense of place as a public health construct. While many recommendations for "good places" are available, few are based on empirical evidence, and thus they are incompatible with current public health practice. Evidence-based recommendations for healthy place making could have important public health implications. Four aspects of the built environment, at different spatial scales-nature contact, buildings, public spaces, and urban form-are identified as offering promising opportunities for public health research, and potential research agendas for each are discussed.

Unmasking delirium.

The authors use a case study to illustrate the risks of delirium in older adult patients and discuss ways to prevent, identify and manage its occurrence. An estimated 60 to 80 per cent of hospitalized frail older adults experience at least one preventable episode of delirium, often leading to prolonged hospitalization, functional decline, increased morbidity and eventual nursing home placement or death. Delirium is a medical emergency, characterized by acute onset and a fluctuating course that is demonstrated by abrupt changes in mental status and function. It has three categories: hyperactive, hypoactive and mixed. Although delirium is amenable to expert nursing care, it is unrecognized or misdiagnosed in up to 70 per cent of older patients. Delirium results from the interplay of multiple forces associated with illness in the older adult, including drugs, substance abuse, metabolic disturbances, nutritional deficiencies, fluid disturbances, acute trauma or illness, infection and impaired physical or functional ability A proactive strategy for delirium prevention and treatment targets defined risk factors and the management of physiologic factors that precipitate delirium. It includes assessment, therapeutic environmental modification, standardized protocols for physiological interventions and staff education.

Evidence-based design can improve health outcomes, study says.

Despite the availability of hundreds of evidence-based studies, many hospitals--caught up in a wave of new construction and development--are running afoul of the cardinal rule of medicine: First, do no harm, says a new industry report.

Improving software environments through usability and interaction design.

This paper introduces the fields of usability and interaction design in order to highlight their benefits and provide further resources for those that wish to find out more. It is hoped that this review will encourage medical illustrators to adopt certain principles and practices in their own project work, in order to strive towards (and ultimately produce) products and environments that provide more positive interactions for their users. Usability and interaction design are fields of study concerned with aims relating to ensuring that any given interactive product or environment is efficient, effective and safe to use, as well as easy to learn and remember. Of primary importance is the experience of the user whose interactions should be positive, as opposed to frustrating or counter-intuitive.

Model assessments of the optimal design of nature reserves for maximizing species longevity.

Using a computational model for the population growth and dispersal of a model species in a fluctuating environment, we test three nature reserve geometries (one large, many small, and a self-similar distribution of reserve sizes) to determine which geometry maximizes species longevity. The self-similar distribution is a close approximation to the distribution of managed areas in the conterminous United States. We consider models with and without migration from or between reserve fragments and both short- and long-range dispersal mechanisms. The optimal geometry depends on the type of dispersal and on the relative probability of survival in protected and non-protected areas. When no migration is allowed from or between reserve fragments of the three geometries, many small equally sized reserves are the optimal geometry. When migration is allowed, the optimal geometry is a single large reserve when the survivability in non-protected areas is low and a self-similar distribution when the survivability is high.

Links between the social and physical environments.

This article proposes a model for understanding the links between children's health and the social and physical environment. School is the principal setting explored as a way of illustrating the issues. Three case examples of school-related problems are presented and actions that pediatricians and others may take are outlined.
