Dialettica del rudere urbano: storia di un isolato Shikumen a Shanghai
No full textRegeneration and renewal are the contemporary topics for the management activities in historical areas of Shanghai. Introducing a personal experience, the author argues the main projects which have affected the historical compounds in Shanghai during the last twenty years, with particular reference to the Shikumen block (typical housing since the urban expansion in the late XIX century). The building in Shikumen style, characterized by terraced houses with high population density and inhabited by lower working classes until today, behind the name of restoration has been replaced with low population density building addressed to reach people, as gentrification strategy. The constructions are quite often rebuilt in the same style with a particular mix of invention and anastilosi or new parts in contemporary style
Increased maternal/fetal blood S100B levels following systemic endotoxin administration and periventricular white matter injury in preterm fetal sheep
No full textObjective. Intrauterine infection is suggested to cause perinatal brain white matter injury. In the current study, we evaluated whether S100B, a brain damage marker, may be also assessed in maternal bloodstream after white matter injury induced by fetal intravenous application of lypopolisaccharide (LPS) endotoxin. Methods. Fourteen fetal sheeps were chronically catheterized at a mean gestational age of 107 days. Three days after surgery, fetuses (n = 7) received 500 ng of LPS or 2 mL 0.9% saline (n = 7) intravenously (IV). Lypopolisaccharide and placebo groups were monitored by continuous hemodynamic data recordings and at 6 predetermined time points (control value; 3, 6, 24, 48, and 72 hours after LPS/placebo administration) blood was drawn for laboratory parameters and S100B assessment. Brain damage was evaluated by light microscopy after Klüver-Barrera staining. Selected areas of the periventricular white matter were also examined by electron microscopy. Results. White matter injury was detected in all LPS-treated fetuses, whereas no abnormalities were seen in control animals or in LPS-treated mothers. Maternal and fetal S100B protein levels were significantly higher in the LPS group than in the control group at all monitoring time points (P <.001). The highest fetal-maternal S100B levels were observed at 3-hour time-point (P <.001). Conclusions. We found that S100B protein is increased in the maternal district in presence of fetal periventricular brain white matter injury induced by endotoxin. The present data offer additional support for S100B assessment in the maternal circulation in pregnancies complicated by intrauterine infection at risk of white matter injury. © 2009 The Author(s)
Effectiveness of different local actions to control vitamin D prescription in Italy
No full textIntroduction. In the last decade, the significant expenditure and consumption increase of vitamin D in Italy led some regions to adopt strategies to improve prescribing appropriateness and contain expenditure.
Materials and methods. Using the statistical analysis method of interrupted time series for consumption and expenditure of cholecalciferol, different types of interventions adopted in four Italian regions and their efficacy were evaluated.
Results. Molise achieved the best results by adopting a health professionals’ education program in addition to a prescriber-sanction system. Emilia-Romagna also opted for a medical education strategy, but the results were less relevant due to the lack of penalties.
Lazio obtained a slowdown in consumption growth by targeting on the utilization of lower-cost per defined daily dose (DDD) packs and adopting a therapeutic plan. Sardinia showed a decrease in expenditure by adopting a target threshold of lower-cost formulation.
Conclusion. The reimbursement of the lowest-cost packs within the National Health Service (NHS) undoubtedly influences spending trend, but it does not solve prescriptive inappropriateness
Understanding Factors Associated With Psychomotor Subtypes of Delirium in Older Inpatients With Dementia
No full textObjectives: Few studies have analyzed factors associated with delirium subtypes. In this study, we investigate factors associated with subtypes of delirium only in patients with dementia to provide insights on the possible prevention and treatments. Design: This is a cross-sectional study nested in the “Delirium Day” study, a nationwide Italian point-prevalence study. Setting and Participants: Older patients admitted to 205 acute and 92 rehabilitation hospital wards. Measures: Delirium was evaluated with the 4-AT and the motor subtypes with the Delirium Motor Subtype Scale. Dementia was defined by the presence of a documented diagnosis in the medical records and/or prescription of acetylcholinesterase inhibitors or memantine prior to admission. Results: Of the 1057 patients with dementia, 35% had delirium, with 25.6% hyperactive, 33.1% hypoactive, 34.5% mixed, and 6.7% nonmotor subtype. There were higher odds of having venous catheters in the hypoactive (OR 1.82, 95% CI 1.18-2.81) and mixed type of delirium (OR 2.23, CI 1.43-3.46), whereas higher odds of urinary catheters in the hypoactive (OR 2.91, CI 1.92-4.39), hyperactive (OR 1.99, CI 1.23-3.21), and mixed types of delirium (OR 2.05, CI 1.36-3.07). We found higher odds of antipsychotics both in the hyperactive (OR 2.87, CI 1.81-4.54) and mixed subtype (OR 1.84, CI 1.24-2.75), whereas higher odds of antibiotics was present only in the mixed subtype (OR 1.91, CI 1.26-2.87). Conclusions and Implications: In patients with dementia, the mixed delirium subtype is the most prevalent followed by the hypoactive, hyperactive, and nonmotor subtype. Motor subtypes of delirium may be triggered by clinical factors, including the use of venous and urinary catheters, and the use of antipsychotics. Future studies are necessary to provide further insights on the possible pathophysiology of delirium in patients with dementia and to address the optimization of the management of potential risk factors
