[Shared decision-making in metaclinical medicine: from informed consent to shared probability].

At the dawn of "metaclinical medicine" era, shared decision-making represents the overcoming of modern medicine guidelines and classical medicine experience. The patient's life plan, the doctor's health plan, the scientist's evidence-based plan, the administrator's plan and the beliefs of the society for healthcare options should be integrated into the shared decision-making process to avoid patient's unrealistic expectations, doctor's self-referential and defensive medicine, the science without compassion of the scientist, the administered medicine of the politician, the herd mentality of artificial intelligence. For a doctor who must evaluate according to science and conscience, it becomes difficult to make decisions about a patient who thinks that there can be "no decisions about me without me".

[Process to insulin for type 2 diabetes mellitus therapy].

In type 1 diabetes mellitus and in symptomatic and critical hyperglycemic states, insulin is a lifesaving drug; however, its value in long-term type 2 diabetes therapy, which represents more than 90% of diabetes, has not been assessed. This happens despite the fact that, in randomized studies on type 2 diabetes, insulin is used in two-thirds of cases when intensive hypoglycemic treatment is needed and in half of the patients when treatment is the standard one. This is a major issue from a clinical, economic and social-health organization point of view as insulin therapy is expensive and needs a complex organization.

[The patient in clinical research: disposable guinea pig or involved actor?].

Background: The request for informed consent to join a clinical trial often creates mistrust and hesitation in the patient who should be enrolled. In our study, we evaluated the reasons for refusing to participate in a clinical trial.

Methods: In the last 10 years of cardiovascular clinical research, we asked an informed consent to 2586 patients for intervention studies.

[Digitalis, a drug to be scrapped?].

We performed a comprehensive review of the scientific literature on the use of digoxin in heart failure and atrial fibrillation. In congestive heart failure (CHF) there is only one randomized trial with a statistical sample sufficiently large. In this trial (DIG trial), which enrolled patients with systolic left ventricular dysfunction in sinus rhythm, digoxin had a neutral action on mortality and modestly reduced the overall need of hospitalization.

General and unspecific damping by malignancy of the circadian amplitude of circulating human melatonin?

The circadian rhythm of serum melatonin of 39 cancer patients is compared with that of 28 healthy subjects matched by gender and age. Each subject provided 6 blood samples at 4-hour intervals for determination of melatonin by RIA. After log10-transformation, data series were analyzed by single and population-mean cosinor and compared between the two groups and among patients subgrouped by cancer site, stage and treatment.
