As a result of the duty of care, the healthcare professional has an obligation of surveillance towards the patients that are under their treatment. According to that principle, the Italian Criminal Supreme Court declared a guilty sentence in many cases of psychiatric patients' suicide, recognizing the criminal liability of the healthcare personnel. This is true not only for suicides occurred inside the hospital, but also for the suicide of psychiatric outpatients. Only in a few cases, the Italian Supreme Court acquitted the healthcare personnel. This happened when it was recognized that the suicide event was unavoidable. Despite the fact that suicide risk is often unpredictable, this does not exclude medical liability. In this work we examine the judicial aspects of five cases of suicide of psychiatric patients, considering whether different preventive strategies could have been effective in preventing the suicide event. This work aims to understand whether the suicide of psychiatric patient is effectively preventable and - referring to healthcare responsibility under penal judgment - if that could be proven beyond all reasonable doubt.

Neurodegenerative diseases (NDs) represent one of the most important public health problems and concerns, as they are a growing cause of mortality and morbidity worldwide, particularly in the elderly. Despite remarkable breakthroughs in our understanding of NDs, there has been little success in developing effective therapies. The use of natural products may offer great potential opportunities in the prevention and therapy of NDs; however, many clinical concerns have arisen regarding their use, mainly focusing on the lack of scientific support or evidence for their efficacy and patient safety. These clinical uncertainties raise critical questions from a bioethical and legal point of view, as considerations relating to patient decisional autonomy, patient safety, and beneficial or non-beneficial care may need to be addressed. This paper does not intend to advocate for or against the use of natural products, but to analyze the ethical framework of their use, with particular attention paid to the principles of biomedical ethics. In conclusion, the notable message that emerges is that natural products may represent a great promise for the treatment of many NDs, even if many unknown issues regarding the efficacy and safety of many natural products still remain.
