Von Willebrand factor (vWf) is a fundamental multimeric plasma glycoprotein in the coagulation process. Its function is to mediate platelet adhesion and to stabilize circulating factor VIII. A functional or quantitative alteration of vWf gives rise to von Willebrand disease (vWD). ⋯ The treatment should be focused both on the control of the acute episode of gastrointestinal bleeding, with vWf replacement therapy and local endoscopic treatment, as well as on the prevention of the progression of angiodysplasia and future bleeding. There are different published therapeutic approaches using vWf replacement that are not effective in all patients. Recently, angiogenesis inhibitor medications have been used.

[Equations to estimate body composition using bioelectrical impedance in Chilean adults].
Equations for the evaluation of fat-free mass (FFM) and fat mass (FM) with Bioelectrical impedance analysis (BIA) were formulated in Caucasian populations. International recommendations suggest that population-specific equations should be formulated. ⋯ Both equations behave similarly and have biases, although less with Schifferli. Statistically correcting for biases, the new adjusted equations provide clinically valid estimates of FFM and FM. Equations should not only be population-specific, but also device-specific.

The assessment of frailty among older people could help to reduce its social and health burden. ⋯ The prevalence of frailty increased markedly with age. It is important to implement prevention strategies to allow an early identification of high-risk individuals.

[Analysis of health care demand subsidies and the role of private health care corporations].
This work analyzes the demand subsidies to access health care and their relationship with large private corporations in Chile, through the transfer of public funds through the modality of freedom of choice (MLE) from 2000 to 2018. Therefore, we analyzed the expansion of the health market and the strengthening of health care corporations, identifying the distribution of resources according to type of health provider. ⋯ We identified an increasing transformation of medical work from free exercise to become dependent on private health corporations, and an increase in public dependence on private providers to meet health demands. There is a growing capture of public funds by these holdings, using the strategy of increasing provider property concentration and a trans nationalization of the health market in Chile.
