In the June issue of The Skeptik 2013 (1) we throwed doubt on h-index, (2) that it is inappropriate for estimation of research scientist ouput, at least for scientists whose h-indexes ranges between 12 - 31. The main problems of h-index is that Dr. Hirsch did not take into account that citations have to be devided by a number of authors on publications. Also, publications were not divided by a number of authors on individual papers (2).

h-index, a missleading value for evaluation of scientist research output

Eight years ago, Dr. Hirsch elaborated systems of mathematical equations for elucidation of individual´s scientific research output (1). This so called h-index was widely accepted in scientific databases. Actually, it appears to be appropriate number to assess research scientist´s impact in the science. However, here we give examples of three slovakian research scientists, working in the same town, under both the area of socialism and capitalism that the use of h-index is not a valid number. (From ethical point of view we cannot give his/her names).

At present, hepatic grafts can be preserved in UW solution by the static preservation for less than 12 hours for good outcome of liver transplantation surgery (1). On the basis of research results from isolated animal perfused livers, we suggest that both a safe preservation of hepatic grafts is possible (for up to18 hours) and that conterporary used liver transplantation process have to be modify according to the following guidliness:

Present outlook on cardiovascular diseases and statins: is scepticism in loco?

The Skeptik 2014;2:1-7

An extreme rise of cardiovascular diseases (CVD) in the twenty century led to the search of new drugs, lowering blood cholesterol levels and a risk of CVD. Discovery of statins was important, because they inhibite competitively HMG-CoA reductase, a key enzyme of cholesterol synthesis. A large number of studies proved that statins deacreased a risk of CVD. Sceptic voices pointed out on side effects of statins (myopathitis and even diabetes). The newest synthetised statins have only minimal side effects. A low risk of side effects of the newest statins, however overlaps a great deacrese of CVD caused by old statins. It is a big mistake to prescribe the newest statins to patients having mildly elevated cholesterol levels for prevention of CVD.
