Study circles improve the precision in nutritional care in special accommodations

Background: Disease-related malnutrition is a major health problem in the elderly population, but it has until recently received very little attention, especially are management issues under-explored. By identifying residents at the risk of undernutrition, appropriate nutritional care can be provided. Objectives: Do study circles and policy documents improve the precision in nutritional care and decrease the prevalence of low or high BMI? Design: Pre and post intervention study. Setting: Special accommodations (nursing homes) within six municipalities were involved. Participants: In 2005, 1726 (90.4%) out of 1910 residents agreed to participate and in 2007, 1526 (81.8%) out of 1866 residents participated. Intervention: Study circles in one municipality, having a policy document in one municipality and no intervention in four municipalities. Measurements: Risk of undernutrition was defined as involving any of: involuntary weight loss, low BMI, and/or eating difficulties. Overweight was defined as high BMI. Results: In 2005 and 2007, 64% of 1726 and 66% of 1526 residents respectively were at the risk of undernutrition. In 2007 significantly more patients in the study circle municipality were accurately provided protein and energy enriched food compared to in the no intervention municipalities. There was a decrease in the prevalence of low BMI in the study circle municipality and the prevalence of overweight increased in the policy document municipality between 2005 and 2007

Aerosol delivery to ventilated newborn infants: historical challenges and new directions

There are several aerosolized drugs which have been used in the treatment of neonatal respiratory illnesses, such as bronchodilators, diuretics, and surfactants. Preclinical in vitro and in vivo studies identified a number of variables that affect aerosol efficiency, including particle size, aerosol flows, nebulizer choice, and placement. Nevertheless, an optimized aerosol drug delivery system for mechanically ventilated infants still does not exist. Increasing interest in this form of drug delivery requires more controlled and focused research of drug/device combinations appropriate for the neonatal population. In the present article, we review the research that has been conducted thus far and discuss the next steps in developing the optimal aerosol delivery system for use in mechanically ventilated neonates

Quantified play: Self-tracking in videogames

This essay develops the concept of “quantified play” to describe and analyze the recent practice of self-tracking in the play of videogames. I argue that statistical, self-tracking utilities in videogames shape how gameplay “appears” and how it is experienced and valued by users. I proceed by situating contemporary self-tracking in games as part of a broader history of play as “quantified.” From there, drawing on interdisciplinary studies of self-tracking, as well as Bernard Stiegler’s postphenomenological analyses of technology, I characterize quantified play in three main ways. First, it is voluntary and occupied with self-knowledge. Second, it is used in mundane or everyday contexts. Third, it relates to the habitual faculty of users. The remainder of the essay illustrates the concept of quantified play through two examples of tracking hardware and software—showing how numerical or statistical apprehensions of player activity (and visualizations thereof) shape how we negotiate videogames.</p

Rethinking the geographies of cultural ‘objects’ through digital technologies: interface, network and friction

This paper addresses how geographers conceptualize cultural artifacts. Many geographical studies of cultural objects continue to depend heavily on an approach developed as part of the ‘new cultural geography’ in the 1980s. That approach examined the cultural politics of representations of place, space and landscape by undertaking close readings of specific cultural objects. Over three decades on, the cultural field (certainly in the Global North) has changed fundamentally, as digital technologies for the creation and dissemination of meaning have become extraordinarily pervasive and diverse. Yet geographical studies of cultural objects have thus far neglected to consider the conceptual and methodological implications of this shift. This paper argues that such studies must begin to map the complexities of digitally-mediated cultural production, circulation and interpretation. It will argue that, to do this, it is necessary to move away from the attentive gaze on stable cultural objects as formulated by some of the new cultural geography, and instead focus on mapping the dynamics of the production, circulation and modification of meaning at digital interfaces and across frictional networks
