Current issues on safety of prokinetics in critically ill patients with feed intolerance

Feed intolerance in the setting of critical illness should be treated promptly given its adverse impact on morbidity and mortality. The technical difficulty of postpyloric feeding tube placement and the morbidities associated with parenteral nutrition prevent these approaches being considered as first-line nutrition. Prokinetic agents are currently the mainstay of therapy for feed intolerance in the critically ill. Current information is limited but suggests that erythromycin or metoclopramide (alone or in combination) are effective in the management of feed intolerance in the critically ill and not associated with significant cardiac, haemodynamic or neurological adverse effects. However, diarrhoea is a very common gastrointestinal side effect, and can occur in up to 49% of patients who receive both erythromycin and metoclopramide. Fortunately, the diarrhoea associated with prokinetic treatments has not been linked to Clostridium difficile infection and settles soon after the drugs are ceased. Therefore, prolonged or prophylactic use of prokinetics should be avoided. If diarrhoea occurs, the drugs should be stopped immediately. To minimize avoidable adverse effects the ongoing need for prokinetic drugs in these patient should be reviewed daily.Nam Q. Nguyen and Swee Lin Chen Yi Me

“If You Can Dream It, You Can Achieve It.” Parent Memorable Messages as Indicators of College Student Success

This study investigated various aspects of parents’ memorable messages about college as they relate to indicators of college student success. Findings revealed that parents’ memorable messages about college focused on working (and playing) hard, the necessity of attending college, providing encouragement and support, and general advice based on parents’ own experiences. Although these message themes were not uniquely predictive of college student success, the students’ perceptions of message and sender characteristics emerged as significant predictors of cognitive learning indicators, learner empowerment, college motivation, and satisfaction with college. Theoretical and practical implications for findings are discussed

The most influential books in Australian sociology (MIBAS), 1963-2003

To mark the 40th anniversary of the Australian Sociological Association (TASA), a survey on the Most Influential Books in Australian Sociology (MIBAS) was conducted. In this article we discuss the MIBAS process, its findings, and provide some reflections on the top 10 most influential books. We also situate the MIBAS survey among other attempts to compile lists of the most influential books in the discipline of sociology, and discuss the benefits and limits of such endeavours. We argue that the MIBAS exercise was useful not only as a commemorative device, but as an opportunity to reflect on the breadth and influence of Australian sociological scholarship

The relationship between basal and induced resistance in Arabidopsis

Plants are constantly exposed to potentially pathogenic micro-organisms. They possess an extensive array of passive and active defense mechanisms, and only a small proportion of micro-organisms are capable of infecting the plant and causing disease. Plant resistance can be broadly defined as the plant's ability to suppress or retard the damaging activity of a pathogen. The most common type of resistance is nonhost resistance. This type of resistance protects the plant entirely from infection by most potential pathogens, and is manifested as an inability of the pathogen to cause disease upon contact with any individual of a particular plant species. In such an interaction, the pathogen is nonpathogenic
