Does ergometric stress test induce a procoagulative condition in patients with previous myocardial infarction
A regularly scheduled physical training program seems to have antithrombotic effects. Moreover, the hemostatic changes occurring in patients with coronary artery disease during acute exercise have not been clearly elucidated. Since stress testing is routinely performed in clinical cardiology, it would be helpful to assess whether patients with coronary artery disease are exposed to acute coronary thrombosis during or soon after sustained physical exercise. This study was designed to evaluate the effect of acute physical exercise (stress test by bicycle ergometer) on blood coagulation in a group of patients with previous myocardial infarction, and to determine whether the antithrombotic therapy commonly administered favorably influences hemostatic equilibrium. Our results suggest that exercise testing is not harmful to patients with previous myocardial infarction in regard to hemostasis and fibrinolysis and that antithrombotic therapy reduces postexercise increase in platelets
Fruit Nutrients of Five Species of Wild Raspberries (Rubus Spp.) From Indonesian Mountain\u27s Forests
Rubus spp. (wild raspberries) is one of genera belongs to Rosaceae, also distributed in the mountain forest of Indonesia. It has a high potency to be cultivated plant. Although, some of the potential of Rubus has already known, information of about fruit nutrients of species that distribute in the mountain forest of Indonesia are not known yet. This study was aimed to determine the fruit nutrients of five species of wild raspberries that was collected in Cibodas Botanical Garden. The results of our experiments demonstrate that the fruits nutrients contents varied among five species of wild raspberries from Indonesian mountain\u27s forests. Rubus fraxinifolius has the highest content of sugar (5.05 g sugar per 100 g fruits) compared to Rubus rosifolius, Rubus chrysophyllus, Rubus lineatus and raspberry. During the ripening and ripe period, there were a different value of vitamin C and iron contents. The highest vitamin C of R. fraxinifolius (83.65 mg/100 gram) on the ripening fruit stage II. On the other hand, the highest vitamin C of R. rosifolius (54.30 mg/100 gram) found on the stage of ripe fruit
The social cost of chronic kidney disease in Italy
This study aims to estimate the mean annual social cost per patient with chronic kidney disease (CKD) by stages 4 and 5 pre-dialyses and cost components in Italy. The multicenter cross-sectional study included all adult outpatients in charge of the 14 main Nephrology Centers of Tuscany Region during 7 weeks from 2012 to 2013. Direct medical costs have been estimated using tariffs for laboratory tests, diagnostic exams, visits, hospitalization and prices for drugs. Non-medical costs included expenses of low-protein special foods, travel, and formal and informal care. Patients' and caregivers' losses of productivity have been estimated as indirect costs using the human capital approach. Costs have been expressed in Euros (2016). Totals of 279 patients in stage 4 and 205 patients in stage 5 have been enrolled. The estimated mean annual social cost of a patient with CKD were a,notsign7422 (+/- a,notsign6255) for stage 4 and a,notsign8971 (+/- a,notsign6503) for stage 5 (p < 0.05). Direct medical costs were higher in stage 5 as compared to stage 4; direct non-medical costs and indirect costs accounted, respectively, for 41 and 5 % of the total social cost of CKD stage 4 and for 33 and 9 % of CKD stage 5. In Italy, the overall annual social cost of CKD was a,notsign1,809,552,398 representing 0.11 % of the Gross Domestic Product. Direct non-medical costs and indirect costs were weighted on the social cost of CKD almost as much as the direct medical cost. Patients, their families and the productivity system sustain the burden of the disease almost as much as the healthcare system. © 2016, The Author(s)
The Materiality of Absence:Organizing and the case of the incomplete cathedral
This study explores the role of absences in making organizing possible. By engaging with Lefebvre’s spatial
triad as the interconnections between conceived (planned), perceived (experienced through practice) and
lived (felt and imagined) spaces, we challenge the so-called metaphysics of presence in organization studies.
We draw on the insights offered by the project of construction of Siena Cathedral during the period 1259–
1357 and we examine how it provided a space for the actors involved to explore their different (civic,
architectural and religious) intentions. We show that, as the contested conceived spaces of the cathedral
were connected to architectural practices, religious powers and civic symbols, they revealed the impossibility
for these intentions to be fully represented. It was this impossibility that provoked an ongoing search for
solutions and guaranteed a combination of dynamism and persistence of both the material architecture of
the cathedral and the project of construction. The case of Siena Cathedral therefore highlights the role
of absence in producing organizing effects not because absence eventually takes form but because of the
impossibility to fully represent it
Un approccio integrato per la valutazione prestazionale della stabilità delle spalle di dighe ad arco
La nota presenta un metodo per valutare le prestazioni sismiche di cunei in roccia alle spalle di una diga ad arco, secondo un approccio agli spostamenti di tipo Newmark opportunamente modificato per includere le forze trasmesse dalla diga e tutti i possibili cinematismi tridimensionali del cuneo all’interno della nicchia di distacco. Nell'ipotesi di blocco rigido e assenza di rotazioni, il metodo è in grado di tenere conto delle tre componenti dell'input sismico, il progressivo distacco del blocco dai piani di appoggio del giunto, l'eventuale recupero del contatto e anche il temporaneo distacco completo del blocco attraverso una fase di volo libero. Oltre alle azioni inerziali gravitazionali e sismiche, sono incluse nell’analisi le forze statiche e dinamiche esercitate al contatto diga-cuneo, comprese quelle relative all'interazione inerziale con l'invaso. Il metodo viene applicato per la verifica sismica della diga ad arco-gravità di Ridracoli (Italia), fondata su una formazione rocciosa fittamente stratificata di origine turbiditica. In particolare, la spalla destra viene verificata rispetto alla formazione di cunei adagiati su piani di strato con caratteristiche di resistenza particolarmente scadenti
