The aim of this laboratory experiment was to examine courtship behavior and reproductive success under two different perceived male densities ill the Alpine newt (Triturus alpestris). Male behavioral patterns were similar at unbiased and male-biased operational sex ratios (OSR). Although the exhibition of hiring behaviors is risky in the presence of other males, no difference in the frequencies of displays was found at the two male, densities. Similarly, the responsiveness of females towards males and the Success rate of the encounters (i.e. spermatophore transfer) were not explained by file OSR. Our results show that courting Alphine newts do not change their courtship patterns when other males are present and do not interact directly. However they are not necessarily opposed to those of previous experiments showing sexual interference awl ,female aversion in male-biased OSR with possibility of interactions. These observations suggest that the evolution of courtship behavior may not be driven by the risk of sexual interference with other males prior to potential physical contact and that the benefits of breeding regardless of OSR can overcome the risk of Competition at male-biased OSR.

Environmental factors are known to have a major effect on behavioral patterns of organisms. Among these factors, temperature particularly affects ectotherms. However, although many studies focused on acoustic communication, the effect of environmental temperature on visual courtship displays and sexual performance has been little explored. The aim of this work was to determine the effect of temperature on the sexual behaviour of the Alpine newt Triturus alpestris in controlled laboratory conditions. Temperature had a major effect on the two sexes: at low temperatures, the frequencies of several displays, including sperm deposition, is lowered. This variation is in fact caused by the female responsiveness, which is temperature-dependent. However, some other behaviours, such as the fanning movement of the male’s tail (i.e., the main courtship display) are directly dependent on temperature: at lower temperatures, the tail beats at a lower rate but for a longer time. The similar reproductive success at the two temperatures indicates that breeding in cold water is not necessarily costly. It allows males and females to mate early in the season. This is particularly adaptive because, in many habitats, the reproductive period is shortened by drying or freezing conditions which may impair survival of branchiate offspring. [less ▲]

Cost related to insulin therapy is markedly increasing in Belgium, as in other Eucopean countries. In the present paper, we will briefly analyze the main reasons for such aa increase, integrate such observation withIn the global context of diabetes management and suggest some solutions to provide best care to insulin-treated diabetic patients at a reasonable cost. The rise of the cost of insulin therapy has a multifactorial origin. It mainly results from an increase in the number of diabetic patients, a more intensive management, In both type 1 and type 2 diabetes, and a greater use of more expansive insulin analogues. It is important to analyze the increase of the cost of insulin therapy within the global burden of diabetes melitus. Only a better responsibility of all health care partners, patients, physicians, pharmaceutical companies, public health authorities, could provide solutions allowing diabetic people to profit from best treatments they should receive in order to prevent diabetic complications, by far the main cause of expenses.

Some health care-related practices are probably on the rise as a response to the political economy. In particular, the therapeutic prescription looking for a diagnostic information allows to escape from a possible overcharge linked to proper diagnostic methods. The cost of such practice is not negligible. In fact, the best way to handle the problem is to reinstate some simple and cheap diagnostic tests in the daily practice of clinicians. The opening of the health care disciplines to new categories of non-physician workers is about to create further problems with regard to the health economics. The unsettled diagnosis and the therapeutic limitation to a quasi-placebo effect will never be positive factors in the global gestion of pathologies. [less ▲]

Type 2 diabetes mellitus is a common chronic disease whose economic impact on both patients and society is constantly increasing. "The Cost of Diabetes in Europe--Type 2 study" is the first coordinated attempt to measure total healthcare costs of type 2 diabetes mellitus in Europe. On average, 3% of the population with type 2 diabetes accounted for 5% of the total healthcare expenditure. Complications have a substantial impact on the costs of managing type 2 diabetes. The prevention of complications, especially cardiovascular disease, will potentially reduce overall healthcare expenditure. [less ▲]
