Ethanol is known to have both γ-Aminobutyric acid agonist and Nmethyl- D-aspartate antagonist characteristics similar to commonly used volatile anesthetic agents. Recent evidence demonstrates that autophagy can reduce the development of ethanol induced neurotoxicity. Recent studies have found that general anesthesia can cause longterm impairment of both mitochondrial morphogenesis and synaptic transmission in the developing rat brain, both of which are accompanied by enhanced autophagy activity. Autophagy may play an important role in general anesthetic mediated neurotoxicity. ⋯ Autophagy may play a role in the development of anesthetic related neurotoxicity. Understanding this may lead to strategies or therapies aimed at preventing or ameliorating general anesthetic agent mediated neurotoxicity.

Chronic pain states are clinically relevant and yet unsolved conditions impacting on quality of life and representing an important social and economic burden; these diseases are poorly treated with the currently available drugs, being urgent the need of innovative analgesics. In this frame, novel analogues of endomorphin-1 and dermorphin emerge as promising starting points to develop innovative, more effective analgesics to treat neuropathic pain. ⋯ This review reports that innovative opioid peptides will be of great help in better understanding the multifaceted scenario of neuropathic pain treatment, providing very interesting opportunities for the identification of novel and more effective opioid analgesics to be employed as medications.

Although survival of patients with different types of cancer has improved, cardiotoxicity induced by anti-neoplastic drugs remains a critical issue. Cardiac dysfunction after treatment with anthracyclines has historically been a major problem. However, also targeted therapies and biological molecules can induce reversible and irreversible cardiac dysfunction. ⋯ Moreover, PD-1 and PD-L1 can be expressed in rodent and human cardiomyocytes. During the last years several cases of fatal heart failure have been documented in melanoma patients treated with checkpoint inhibitors. The recent experience with cardiovascular toxic effects associated with checkpoint inhibitors introduces important concepts biologically and clinically relevant for future oncology trials and clinical practice.

Fabry disease is an X-linked lysosomal storage disorder caused by deficient activity of α -galactosidase A which leads to progressive intracellular accumulation of globotriaosylceramide in tissues and organs including heart, kidney, vascular endothelium, the nervous system, the eyes and the skin. Cardiac involvement is common, leads to fatal complications and is mainly responsible for reduced life expectancy in Fabry disease. The exact staging of disease progression and timely initiation of treatment is essential in Fabry disease. Therefore, it is essential to use the possibilities of specific biomarkers for early detection of organ involvement or early diagnosis. ⋯ In conclusion, we suggest to measure lyso-GB3 and hsTNT at least once a year. The routine measurement of these two biomarkers will help now for the staging of every individual patient and in addition, will help for a better general understanding of Fabry disease.

Elevated triglyceride levels (higher than ~1000 mg/dL) are associated with an increased risk for pancreatitis. Apolipoprotein-CIII (apoC-III) plays a key role in the metabolism of triglycerides and triglyceride-rich lipoproteins. ⋯ The antisense oligonucleotide (ASO) against APOC3 mRNA volanesorsen (previously called ISIS 304801, ISIS-ApoCIIIRx and IONIS-ApoCIIIRx) robustly decreases both, apoC-III production and triglyceride concentrations and is being currently evaluated in phase 3 trials. In this narrative review, we present the currently available clinical evidence on the efficacy and safety of volanesorsen for the treatment of hypertriglyceridemia.
