In the area of Emergency Room (ER), many patients present criteria compatible with a SIRS, but only some of them have an associated infection. The new definition of sepsis by the European Society of Intensive Care Medicine and the Society of Critical Care Medicine (2016), revolutionizes precedent criteria, overcoming the concept of SIRS and clearly distinguishing the infection with the patient’s physiological response from the symptoms of sepsis. Another fundamental change concerns the recognition method: The use of SOFA (Sequential-Sepsis Related-Organ Failure Assessment Score) as reference score for organ damage assessment. Also, the use of the qSOFA is based on the use of three objective parameters: Altered level of consciousness (GCS <15 or AVPU), systolic blood pressure ≤ 100 mmHg, and respiratory rate ≥ 22/min. If patients have at least two of these altered parameters in association with an infection, then there is the suspicion of sepsis. In these patients the risk of death is higher, and it is necessary to implement the appropriate management protocols, indeed the hospital mortality rate of these patients exceeds 40%. Patients with septic shock can be identified by the association of the clinical symptoms of sepsis with persistent hypotension, which requires vasopressors to maintain a MAP of 65 mmHg, and serum lactate levels >18 mg/dL in despite of an adequate volume resuscitation. Then, patient first management is mainly based on: (1) Recognition of the potentially septic patient (sepsis protocol-qSOFA); (2) Laboratory investigations; (3) Empirical antibiotic therapy in patients with sepsis and septic shock. With this in mind, the authors discuss the most important aspects of the sepsis in both adults and infants, and also consider the possible treatment according current guidelines. In addition, the possible role of some nutraceuticals as supportive therapy in septic patient is also discussed.

Hepatocellular carcinoma (HCC) is nowadays the sixth cause of tumour-related deceases worldwide, estimated to become the third in Western countries by 2030. New drugs for HCC treatment still have many adverse effects. Several lines of evidence indicate that plant metabolites offer concrete opportunities for developing new therapeutic strategies for many diseases, including cancer. We previously reported that ethyl acetate extract of a spontaneous edible plant harvested in Apulia, Crithmum maritimum, significantly inhibited cell growth in HCC cells. By 1H-NMR spectroscopy, here we show that Crithmum maritimum ethyl acetate extract counteracts the Warburg effect, by reducing intracellular lactate, inhibits protein anabolism, by decreasing amino acid level, and affects membrane biosynthesis by lowering choline and phosphocholine. Also, we observed an effect on lipid homeostasis, with a reduction in triglycerides, cholesterol, monounsaturated fatty acids (MUFA), and diunsaturated fatty acids (DUFA), and an increase in polyunsaturated fatty acids (PUFA). Taken together, these data demonstrate that Crithmum maritimum-induced cytostasis is exerted through a multi-effect action, targeting key metabolic processes in HCC cells. Overall, our findings highlight the role of Crithmum maritimum as a promising tool for the prevention and the improvement of the therapeutic options for HCC and other types of tumours.

Background: There is not a time in the history when epidemics did not loom large: infectious diseases have always had civilisation and evolution-altering consequences. Throughout history, there have been a number of pandemics: cholera, bubonic plague, influenza, smallpox are some of the most brutal killers in human history. Historical accounts of pandemics clearly demonstrate that war, unhygienic conditions, social and health inequality create conditions for the transmission of infectious diseases, and existing health disparities can contribute to unequal morbidity and mortality. The Renaissance was a period of European cultural, artistic, political and economic “rebirth” following the Middle Ages, but it was also the time when new infectious disease appeared, such as Syphilis. The epidemic spread of Syphilis began between the late 15th century and early 16th century due to the increased migration of peoples across Europe. The rapid spread of venereal syphilis throughout Europe suggests the introduction of a disease into a population that had not previously been exposed. Syphilis is a type of treponematosis, which includes syphilis, bejel, yaws, and pinta, but, while syphilis is venereal disease, the others are nonvenereal. Syphilis was, at the beginning, a disease of great severity due to its novelty, as the population had no time to gain any immunity against this venereal disease. Methods: The purpose of this study is to investigate the origin of syphilis and the evolution of the treatments from the empiric means to the discovery of penicillin, but also to understand how this venereal disease has largely influenced human lifestyle and evolution. Conclusions: The first of the three hypotheses about its origins is the Columbian hypothesis, which states that Columbus's crew acquired syphilis from Native Americans and carried it back to Europe in 1493 A. D. On the contrary, the second hypothesis (pre-Columbian) asserts that syphilis was present in Europe long before Columbus's voyage and was transferred to the New World by Columbus's men. The Unitarian theory argues that syphilis, bejel, yaws, and pinta are not separate diseases but they represent syndromes caused by slightly different strains of one organism. Nowadays, Syphilis’ origin is still uncertain and remains controversial. However, the large impact on the social behavior and international public health is an important reason to investigate about its origins and how to prevent the transmission.

Objectives Hepatocellular carcinoma (HCC) is one of the most frequent tumours worldwide and available drugs are inadequate for therapeutic results and tolerability. Hence, novel effective therapeutic tools with fewer side effects are of paramount importance. We have previously shown that Crithmum maritimum ethyl acetate extract exerts a cytostatic effect in HCC cells. Here, we tested whether C. maritimum ethyl acetate extract in combination with half sorafenib IC50 dose ameliorated efficacy and toxicity of sorafenib in inhibiting liver cancer cell growth. Moreover, we investigated the mechanisms involved. Methods Two HCC cell lines (Huh7 and HepG2) were treated with C. maritimum ethyl acetate extract and half IC50 sorafenib dose usually employed in vitro. Then, cell proliferation, growth kinetics and cell toxicity were analysed together with an investigation of the cellular mechanisms involved, focusing on cell cycle regulation and apoptosis. Key findings Results show that combined treatment with C. maritimum ethyl acetate extract and half IC50 sorafenib dose decreased cell proliferation comparably to full-dose sorafenib without increasing cell toxicity as confirmed by the effect on cell cycle regulation and apoptosis. Conclusions These results provide scientific support for the possibility of an effective integrative therapeutic approach for HCC with fewer side effects on patients.

Aim: Investigating about the history of allergies and discovery of the histamine’s role in the immune response through historical references, starting with ancient anecdotes, analysing the first immunization attempts on animals to understand its importance as the anaphylaxis mediator. Moreover, we shortly resume the most recent discoveries on mast cell role in allergic diseases throughout the latest updates on its antibody-independent receptors. Methods: Publications, including reviews, treatment guidelines, historical and medical books, on the topic of interest were found on Medline, PubMed, Web of Knowledge, Web of Science, Google Scholar, Elsevier’s (EMBASE.comvarious internet museum archives. Texts from the National Library of Greece (Stavros Niarchos Foundation), from the School of Health Sciences of the National and Kapodistrian University of Athens (Greece). We selected key articles which could provide an historical and scientific insight into histamine molecule and its mechanism of action’s discovery starting with Egyptian, Greek and Chinese antiquity to end with the more recent pharmacological and molecular discoveries. Results: Allergic diseases were described by medicine since ancient times, without exactly understanding physio-pathologic mechanisms of immuno-mediated reactions and of their most important biochemical mediator, histamine. Researches on histamine and allergic mechanisms started at the beginning of the 20th century with the first experimental observations on animals of anaphylactic reactions. Histamine was then identified as their major mediator of many allergic diseases and anaphylaxis, but also of several physiologic body’s functions, and its four receptors were characterized. Modern researches focus their attention on the fundamental role of the antibody-independent receptors of mast cells in allergic mechanisms, such as MRGPRX2, ADGRE2 and IL-33 receptor. Conclusion: New research should investigate how to modulate immunity cells activity in order to better investigate possible multi-target therapies for host’s benefits in preclinical and clinical studies on allergic diseases in which mast cells play a major role.
