The relationship between electrophysiological correlates of recollection and amount of information retrieved

The electrophysiological correlates of recollection were investigated with a modified Remember/Know task in which subjects signaled whether they fully or partially recollected visual object information in each study episode. A positive-going ERP deflection--the left parietal old/new effect--was sensitive to the amount of information recollected, demonstrating greater amplitude when elicited by test items associated with full relative to partial recollection. These findings support prior proposals that the left parietal ERP old/new effect is sensitive to the amount of information recollected from episodic memory. An early-onsetting (ca. 150 ms), left frontal old/new effect differentiated items accorded correct old versus correct new responses regardless of whether the items were endorsed as familiar or recollected. This finding extends the range of circumstances under which early, frontally distributed old/new effects occur, and adds weight to previous suggestions that these effects are a neural correlate of familiarity-driven recognition memory.     

Climate change transformation: A definition and typology to guide decision making in urban environments

Climate change presents a threat to the sustainability of cities and their societies, and must be adequately addressed. Urban environments (cities) are responsible for the creation of a significant amount of greenhouse gas emissions which are the source of climate change. Cities have been increasingly the focus of action to address climate change, yet emissions are not significantly reducing. Additionally, there a lack of integration between adaptation and mitigation. This prevents responses adequate to limit global warming to 1.5^OC, and to be well adapted to anticipated changes. This paper critically analyses existing definitions and typologies of climate change actions. A definition of ‘climate change transformation’ is proposed which includes the integration of adaptation and mitigation goals to enable a new regime in which global warming is limited to 1.5^OC. A new three-part typology: ‘coping, malaction and transformation,’ is presented for categorising climate change actions by the extent to which they integrate adaptation and mitigation, and define a new regime. The typology is accompanied by illustrations to demonstrate the relationship between adaptation and mitigation. The definition, typology and illustration serve to guide effective climate change decision making, and provides principles to guide application in urban environments.     

Development of shock wave assisted therapeutic devices and establishment of shock wave therapy

In order to exploit systems for shock wave therapy, we are working for the development of clinical devices that are based on the concept of shock waves or related phenomena. The paper describes these new therapeutic devices designed for the minimally invasive approach to vascular thromboloysis, selective dissection of tissues, and drug or DNA delivery. To investigate the response of cells to shock loading, a precise method of shock waves generation in space and time has been developed. This method has been studied for application in cardiovascular therapy, cancer treatment, and cranioplasty in close vicinity of the brain. A laser ablation shock wave assisted particle acceleration device has been developed for delivering drug and DNA into soft targets in the human body. The penetration depth of microparticles observed in the experimental targets is believed to be sufficient for pharmacological treatments. In order to achieve an efficient method for rapid revascularization of cerebral thrombosis, a laser induced liquid jet (LILJ) system has been developed. The LILJ has been successfully applied for selective dissection of soft tissue preserving nerve and blood vessels. The system has been further improved by using piezoelectric actuators to drive the liquid jets, as an alternative to pulse laser.     

Cancel that PICC line order; cholecystostomy tube and short course of antibiotics

Background

Current guidelines do not specifically address optimal antibiotic duration following cholecystostomy. This study compares outcomes for short-course (<7 days) and long-course (≥7 days) antibiotics post-cholecystostomy.

Prevalence of malnutrition in free living elderly people in Iran: a cross-sectional study

INTRODUCTION: The elderly are a particularly vulnerable group. Malnutrition is common and increases an old person's vulnerability to disease. We determine the prevalence of malnutrition in free living elderly people and its relationship with nutritional status and some socioeconomic conditions. METHODS: Nutritional status and its relationship with socioeconomic conditions were evaluated using Mini Nutritional Assessment in free-living elderly people (n=1962 using cluster sampling, 917 male/1045 female, aged>60). RESULTS: Among the population, 42.7% were well nourished, 12.0% malnourished and 45.3% at risk of malnutrition. There was more malnutrition in females compared to males (13% vs. 10.8%; p<0.001), rural than urban (14.8% vs. 9.9%; p<0.001), non educated than educated (13.3% vs 6.9%; p<0.001), lonely than living with family (17.5% vs. 10.3%; p<0.001), unemployed than employed (13.3% vs. 6.3%; p<0.05), elderly on income support (Behsisty charity) compared with elderly on retirement salary, (41.7% vs. 3.3%; p<0.05). Total Mini Nutritional Assessment scores correlated significantly with length of education, age, waist circumference, and body mass index (r =0.426, -0.142, 0.355 and 0.269 respectively). CONCLUSION: This study revealed a 12% malnutrition prevalence in this elderly group, with higher percentages in special socioeconomic conditions. Health care providers need to be aware of this problem and its scope. These results reinforce the need to screen, monitor and support elderly people.
