BACKGROUND: Vasospasm is the major cause of morbidity and mortality after aneurysmal subarachnoid hemorrhage. It is well known that the vasoreactivity decreases with advancing age, but it is not well investigated in a large patient cohort whether, as a consequence, the incidence of vasospasm is lower in elderly patients. OBJECTIVE: To investigate whether transcranial Doppler vasospasm, delayed ischemic neurological deficits, and vasospasm-associated ischemic lesions are less frequent in older patients. METHODS: Seven hundred fifty-eight patients who suffered from subarachnoid hemorrhage were included in this study. Clinical presentation, Hunt and Hess score, Fisher grade, incidence of vasospasm, neurological deficits and ischemic lesions on radiographic imaging, transcranial Doppler blood flow velocities, medical complications, and outcome were registered. RESULTS: Four hundred seventy-eight patients = 60 years of age were identified; 55.2% of the younger and 25.7% of the older age group developed post-hemorrhagic vasospasm (P = 60 years of age

Besides, it forces the companies to "include" the possibility of widerdifferentiation of the goods in the price. However, generally, such differentiation— is psychological, instead of real. But in this case, the company is not inadvantage for long, especially when economical situation allows a quick adoptingof any innovation.The companies should get the idea that consumers become more educated andhave the best toolkit, such as the Internet, for example. It makes them more legibleat goods purchase.The processes of globalization, a hyper competition and the Internet influenceon marketing along with formation of the markets and business activity. All thethree factors put additional pressure upon the prices. As a result of globalizationcompanies transfer the manufacture to more cheaply areas, and import the goodsunder the prices lower that local sellers establish. The hyper competition means agreat number of the suppliers struggling for the same consumers, and it also leadsto reduction of price. The Internet allows people to compare the prices quickly andto take advantage of the cheapest offer. Thus, the marketing problem consists offinding the ways of controlling a price level and profitableness, according to thelisted macro- tendencies. National manufacturers will not keep the consumers ifthey can’t be the constant leaders offering the greatest value.At the same time various world regions, being more and more integrated intoeconomic, often sin with protectionism. The local companies demand granting ofconcessionary terms from other participants of the market in region. But artificialtrading preferences cannot exist for a long time, without being accompanied byconsiderable decrease in value for the consumer.In marketing it is possible to include following changes in the list of newtendencies:• From type marketing "make and sell" to marketing "hear and respond";• From possession of actives to possession of brands;• From vertical integration to integration virtual (outsourcing);• From mass marketing to the marketing focused on inquiries of the consumer;• From activity only in the market to additional work in a cyberspace;• From a competition for a market share to a competition for certain theconsumer;• From efforts on attraction of the new consumer to preservation andsatisfaction already existing;• From marketing of transactions to marketing of mutual relations withclients;• From intermediary marketing to the direct;• From a marketing monologue to dialogue with the consumer;• From separate planning of kinds of communications to the integratedmarketing communications;• From single-channel marketing to the multichannel;• From the marketing concentrated to the goods, to the marketing concentratedon interests of the consumer;• From marketing activity by forces of one department to marketing in whichall employees of the company are engaged;• From operation of suppliers and distributors to partnership with them.Traditionally marketing activity assumed the professional use of the followingtooling: sales representatives, advertising, sales promotion and marketingresearches. Each company should deal with this toolkit in perfection. Butmarketing divisions need to master and new skills, among which — brand creation,management of mutual relations with clients, marketing and information searchwith use of databases, telephone marketing, marketing of impressions, and also theanalysis of profitableness of the separate goods, a segment of the market, thedistribution and consumer channel.Not far off is the time when access to the information in a mode of real timewill strongly influence marketing practice. Process of acceptance of marketingdecisions becomes objective: the authentic data will arrive from the market andwill be analyzed by means of computer programs of supporting the decisions,allowing to model consequences of those or other actions. It is the way the modernarmy works, some companies apply the same methods; for example, leading aircarriers use special "a game room" for modelling of "military operations" inmarketing.The main economic problem is superfluous capacities. How should one get ridof it?In practice each branch of economy suffers from overproduction. The worldautomobile industry could, probably, let out 30 % more of cars, without installingany new factory. The same is possible to tell about the steelmaking and chemicalindustry. The deficiency of buyers and surplus of the goods is everywhere.Superfluous capacities are result of excessive optimism of the companies-manufacturers. Many companies planned 10 percent growth of sales but the ofmarket growth risen only by 3%. As a result there is overproduction and a hyper-competition which, in turn, inevitably lead to prices falling.The basic ways of protection:1) creation of a powerful brand;2) formation of an audience of the loyal consumers, ready to pay higher price;3) consolidation.
