Eating in table-service restaurants has been implicated as a risk factor for Escherichia coli O157:H7 infection. To explore this association and learn about the prevalence of risky ground beef preparation practices in restaurants, the Environmental Health Specialists Network (EHS-Net) assessed ground beef handling policies and practices in restaurants in California, Colorado, Connecticut, Georg...

BACKGROUND AND AIMS Celiac sprue is a life-long disease characterized by an intestinal inflammatory response to dietary gluten. A gluten-free diet is an effective treatment for most patients, but accidental ingestion of gluten is common, leading to incomplete recovery or relapse. Food-grade proteases capable of detoxifying moderate quantities of dietary gluten could mitigate this problem. MET...

Providing astronauts with healthy, appetizing and diverse meals from materials that can be easily stored and transported into space, is a critical ongoing problem in space travel and exploration. Here, we propose a radical new approach to creating meals in space. Our ultimate aim is to design a portable food preparation and production machine, capable of creating food items that emulate the tas...

One way in which technology can help people with cognitive impairments to stay independent for longer is through situational support systems that recognize a person’s activities and provide help if needed. While food preparation is one of the most important tasks of daily living, such activities are extremely challenging to recognize automatically as they involve a large number of different obj...

Diarrhea is a leading cause of death among children under 5 years of age worldwide. Flies are important vectors of diarrheal pathogens in settings lacking networked sanitation services. There is no standardized method for measuring fly density in households; many methods are cumbersome and unvalidated. We adapted a rapid, low-cost fly enumeration technique previously developed for industrial se...

Solid-Phase Extraction (SPE) is a sample preparation method that is practised on numerous application fields due to its many advantages compared to other traditional methods. SPE was invented as an alternative to liquid/liquid extraction and eliminated multiple disadvantages, such as usage of large amount of solvent, extended operation time/procedure steps, potential sources of error, and high ...

OBJECTIVE To examine the association between frequency of assisting with home meal preparation and fruit and vegetable preference and self-efficacy for making healthier food choices among grade 5 children in Alberta, Canada. DESIGN A cross-sectional survey design was used. Children were asked how often they helped prepare food at home and rated their preference for twelve fruits and vegetable...

BACKGROUND Instrumental activities of daily living (IADL) start to decline during the progression of amnestic mild cognitive impairment (aMCI) to Alzheimer disease (AD). Cognitive and physical decline are involved in the loss of functional independence. However, little is known about AD-related neural change that leads to IADL impairment. The purpose of this study was to clarify the effects of ...

INTRODUCTION Little is reported about how much time patients spend on self-management, a cornerstone of diabetes care. METHODS We studied a cross-section of 1482 diabetic patients enrolled in 3 northeastern United States managed care plans. Patients were surveyed about how much time they spent on foot care, exercise, and food shopping/preparation (7/00 to 9/01). Logistic regressions modeled w...
