El Tabac al món : la indústria a nivell local i global, legislació, problemes i reptes de futur

Per què a un fumador del Canadà li costa 10 vegades més diners comprar un paquet de tabac que el que li costa a un fumador de Cuba? Què se n’ha fet dels anuncis de Marlboro als cotxes de l’escuderia automovilística Ferrari? Comés que s’han creat espais reservats per a fumadors en els últims anys? Aquestes i altres preguntes sobre el món del tabac conformen l’objecte del nostre treball d’investigació. El nostre propòsit és intentar donar resposta a qüestions com aquestes, i fer que el lector entengui realment a què es deuen aquests canvis en l’estructura del mercat del tabac. Mostrarem, mitjançant una mirada analítica dels diferents factors, que gran part d’aquests efectes en un producte (com pot ser el cigarret, en el cas que ens ocupa) són extrapolables a altres béns i que es poden explicar des del punt de vista econòmic, examinant les decisions d’agents amagats com ara el govern, i considerant les repercussions dels diferents tipus de polítiques.Com tots sabem, el món actual està conformat per un seguit de relacions entre individus, o millor dit, agents econòmics que interactuen entre ells. Els resultats d’aquestes interaccions determinen el comportament de variables que, ben definides, poden ser estudiades, així com els seus efectes. Nosaltres hem intentat mostrar d’una manera senzilla i a l’abast de tothom fins a quin punt arriben aquestes interrelacions. El que preteníem en tot moment basar-nos en dades objectives obtingudes previ estudi. Es per això que, de la mateixa manera que al acabar el treball el lector serà capaç d’entendre per què varia elpreu del mateix bé al creuar una frontera, queda a càrrec de cadascú determinar si, per exemple, els fumadors són objectes de persecució o de si les mesures paternalistes del govern envers la prohibició de la publicitat estan justificades.

Geographic variation in the frequency of isolation and fluconazole and voriconazole susceptibilities of Candida glabrata: an assessment from the ARTEMIS DISK Global Antifungal Surveillance Program.

Geographic differences in frequency and azole resistance among Candida glabrata may impact empiric antifungal therapy choice. We examined geographic variation in isolation and azole susceptibility of C. glabrata. We examined 23 305 clinical isolates of C. glabrata during ARTEMIS DISK global surveillance. Susceptibility testing to fluconazole and voriconazole was assessed by disk diffusion, and the results were grouped by geographic location: North America (NA) (2470 isolates), Latin America (LA) (2039), Europe (EU) (12 439), Africa and the Middle East (AME) (728), and Asia-Pacific (AP) (5629). Overall, C. glabrata accounted for 11.6% of 201 653 isolates of Candida and varied as a proportion of all Candida isolated from 7.4% in LA to 21.1% in NA. Decreased susceptibility (S) to fluconazole was observed in all geographic regions and ranged from 62.8% in AME to 76.7% in LA. Variation in fluconazole susceptibility was observed within each region: AP (range, 50-100% S), AME (48-86.9%), EU (44.8-88%), LA (43-92%), and NA (74.5-91.6%). Voriconazole was more active than fluconazole (range, 82.3-84.2% S) with similar regional variation. Among 22 sentinel sites participating in ARTEMIS from 2001 through 2007 (84 140 total isolates, 8163 C. glabrata), the frequency of C. glabrata isolation increased in 14 sites and the frequency of fluconazole resistance (R) increased in 11 sites over the 7-year period of study. The sites with the highest cumulative rates of fluconazole R were in Poland (22% R), the Czech Republic (27% R), Venezuela (27% R), and Greece (33% R). C. glabrata was most often isolated from blood, normally sterile body fluids and urine. There is substantial geographic and institutional variation in both frequency of isolation and azole resistance among C. glabrata. Prompt species identification and fluconazole susceptibility testing are necessary to optimize therapy for invasive candidiasis.

Modern Perspectives on Fiscal Stabilization Policies

The present paper describes recent research on two central themes of Keynes General Theory: (i) the social waste associated with recessions, and (ii) the effectiveness of fiscal policy as a stabilization tool. The paper also discusses some evidence on the extent to which fiscal policy has been used as a stabilizing tool in industrial economies over the past two decades.

The effect of sodium tetrathionate stabilization on the distribution of three nuclear matrix proteins in human K562 erythroleukemia cells.

Using both conventional fluorescence and confocal laser scanning microscopy we have investigated whether or not stabilization of isolated human erythroleukemic nuclei with sodium tetrathionate can maintain in the nuclear matrix the same spatial distribution of three polypeptides (M(r) 160 kDa and 125 kDa, previously shown to be components of the internal nuclear matrix plus the 180-kDa nucleolar isoform of DNA topoisomerase II) as seen in permeabilized cells. The incubation of isolated nuclei in the presence of 2 mM sodium tetrathionate was performed at 0 degrees C or 37 degrees C. The matrix fraction retained 20-40% of nuclear protein, depending on the temperature at which the chemical stabilization was executed. Western blot analysis revealed that the proteins studied were completely retained in the high-salt resistant matrix. Indirect immunofluorescence experiments showed that the distribution of the three antigens in the final matrix closely resembled that detected in permeabilized cells, particularly when the stabilization was performed at 37 degrees C. This conclusion was also strengthened by analysis of cells, isolated nuclei and the nuclear matrix by means of confocal laser scanning microscopy. We conclude that sodium tetrathionate stabilization of isolated nuclei does not alter the spatial distribution of some nuclear matrix proteins.

Occipitoaxial spinal interarticular stabilization with vertebral artery preservation for atlantal lateral mass failure.

The treatment of craniocervical instability caused by diverse conditions remains challenging. Different techniques have been described to stabilize the craniocervical junction. The authors present 2 cases in which tumoral destruction of the C-1 lateral mass caused craniocervical instability. A one-stage occipitoaxial spinal interarticular stabilization (OASIS) technique with titanium cages and posterior occipitocervical instrumentation was used to reconstruct the C-1 lateral mass and stabilize the craniocervical junction. The ipsilateral vertebral artery was preserved. The OASIS technique offers single-stage tumor resection, C-1 lateral mass reconstruction, and stabilization with a loadsharing construct. It could be an option in the treatment of select cases of C-1 lateral mass failure.

Global Prospects for Dairy in Argentina and Chile: Evidence from Field Visits and Model Simulations, August 2006

We assess the international competitiveness of the dairy industries in Argentina and Chile, combining recent market intelligence gathered from field visits with quantitative simulations of global policy reform scenarios. Both countries exhibit strong potential for export growth but face significant internal and external barriers to expanding their dairy industries. Global policy reforms would resolve some of the international obstacles to their expansion. Argentina has great potential, but it is handicapped by its current macroeconomic policies, trade policy distortions, and the uncertainty associated with policy implementation. Chile is more limited in terms of natural capacity for expansion, but it has a positive trade and investment environment.

Hormonal, global, and regional haemodynamic responses to a vascular antagonist of vasopressin in patients with congestive heart failure with and without hyponatraemia.

The pathophysiological role of an increase in circulating vasopressin in sustaining global and regional vasoconstriction in patients with congestive heart failure has not been established, particularly in patients with hyponatraemia. To assess this further, 20 patients with congestive heart failure refractory to digoxin and diuretics were studied before and 60 minutes after the intravenous injection (5 micrograms/kg) of the vascular antagonist of vasopressin [1(beta-mercapto-beta,beta-cyclopentamethylene-propionic acid), 2-(0-methyl) tyrosine] arginine vasopressin. Ten patients were hyponatraemic (plasma sodium less than 135 mmol/l) and 10 were normonatraemic. In both groups of patients the vascular vasopressin antagonist did not alter systemic or pulmonary artery pressures, right atrial pressure, pulmonary capillary wedge pressure, cardiac index, or vascular resistances. Furthermore, there was no change in skin and hepatic blood flow in either group after the injection of the vascular antagonist. Only one patient in the hyponatraemic group showed considerable haemodynamic improvement. He had severe congestive heart failure and a high concentration of plasma vasopressin (51 pmol/l). Plasma renin activity, vasopressin, or catecholamine concentrations were not significantly changed in response to the administration of the vasopressin antagonist in either the hyponatraemic or the normonatraemic groups. Patients with hyponatraemia, however, had higher baseline plasma catecholamine concentrations, heart rate, pulmonary pressure and resistance, and lower hepatic blood flow than patients without hyponatraemia. Plasma vasopressin and plasma renin activity were slightly, though not significantly, higher in the hyponatraemic group. Thus the role of vasopressin in sustaining regional or global vasoconstriction seems limited in patients with congestive heart failure whether or not concomitant hyponatraemia is present. Vasopressin significantly increases the vascular tone only in rare patients with severe congestive heart failure and considerably increased vasopressin concentrations. Patients with hyponatraemia do, however, have raised baseline catecholamine concentrations, heart rate, pulmonary arterial pressure and resistance, and decreased hepatic blood flow.

The effects of arterial flow on platelet activation, thrombus growth, and stabilization.

Injury of an arterial vessel wall acutely triggers a multifaceted process of thrombus formation, which is dictated by the high-shear flow conditions in the artery. In this overview, we describe how the classical concept of arterial thrombus formation and vascular occlusion, driven by platelet activation and fibrin formation, can be extended and fine-tuned. This has become possible because of recent insight into the mechanisms of: (i) platelet-vessel wall and platelet-platelet communication, (ii) autocrine platelet activation, and (iii) platelet-coagulation interactions, in relation to blood flow dynamics. We list over 40 studies with genetically modified mice showing a role of platelet and plasma proteins in the control of thrombus stability after vascular injury. These include multiple platelet adhesive receptors and other junctional molecules, components of the ADP receptor signalling cascade to integrin activation, proteins controlling platelet shape, and autocrine activation processes, as well as multiple plasma proteins binding to platelets and proteins of the intrinsic coagulation cascade. Regulatory roles herein of the endothelium and other blood cells are recapitulated as well. Patient studies support the contribution of platelet- and coagulation activation in the regulation of thrombus stability. Analysis of the factors determining flow-dependent thrombus stabilization and embolus formation in mice will help to understand the regulation of this process in human arterial disease.

The Role of Public Administration: A Global Perspective

From my experience with public administration in my country, Cape Verde, and through readings in the area of development administration, I have found that a distinctive role and specific societal goals are usually ascribed to public administration in developing country. In studying American public administration approaches and operation, I was stuck by the fact that the definition of roles and societal goals for public administration seems not to be a forefront concern in the field. How to do things and achieve efficiency, in a managerial and rational perspective, seemed to draw much more attention than the purpose of doing things. Somehow, the contrast with the concept of development administration seemed too sharp, and I became curious about the reasons for such disparate approaches. Historical, cultural, and environmental differences would probably not be the only explanation for that since the concept of development administration was shaped, in the late 50’s and 60’s, by American authors and institutional aid agencies, and then “offered” to developing countries. At the same time, looking to poor results of the successive prescriptions of the development administration movement, I was no sure that such a concept and the framework it establishes was worthwhile. What practical answers and arrangement did they bring to the needs and challenges of public administrations in developing countries? …

Reconciling global mammal prioritization schemes into a strategy.

The huge conservation interest that mammals attract and the large datasets that have been collected on them have propelled a diversity of global mammal prioritization schemes, but no comprehensive global mammal conservation strategy. We highlight some of the potential discrepancies between the schemes presented in this theme issue, including: conservation of species or areas, reactive and proactive conservation approaches, conservation knowledge and action, levels of aggregation of indicators of trend and scale issues. We propose that recently collected global mammal data and many of the mammal prioritization schemes now available could be incorporated into a comprehensive global strategy for the conservation of mammals. The task of developing such a strategy should be coordinated by a super-partes, authoritative institution (e.g. the International Union for Conservation of Nature, IUCN). The strategy would facilitate funding agencies, conservation organizations and national institutions to rapidly identify a number of short-term and long-term global conservation priorities, and act complementarily to achieve them.
