Aspirin Colorectal Cancer Prevention in Lynch Syndrome: Recommendations in the Era of Precision Medicine.

Cancer prevention in the era of precision medicine has to consider integrated therapeutic approaches. Therapeutic cancer prevention should be offered to selected cohorts with increased cancer risk. Undoubtedly, carriers of hereditary cancer syndromes have a well-defined high cancer risk. Lynch Syndrome is one of the most frequent hereditary syndromes; it is mainly associated with colorectal cancer (CRC). Nonsteroidal anti-inflammatory drugs and, in particular, aspirin use, has been associated with reduced CRC risk in several studies, initially with contradictory results; however, longer follow-up confirmed a reduced CRC incidence and mortality. The CAPP2 study recruited 861 Lynch syndrome participants randomly assigned to 600 mg of aspirin versus placebo. Like sporadic CRCs, a significant CRC risk reduction was seen after an extended follow-up, with a median treatment time that was relatively short (2 years). The ongoing CAPP3 will address whether lower doses are equally effective. Based on pharmacology and clinical data on sporadic CRCs, the preventive effect should also be obtained with low-dose aspirin. The leading international guidelines suggest discussing with Lynch syndrome carriers the possibility of using low-dose aspirin for CRC prevention. We aim systematically promote this intervention with all Lynch syndrome carriers.

Effect of EPA on Neonatal Pig Sertoli Cells "In Vitro": A Possible Treatment to Help Maintain Fertility in Pre-Pubertal Boys Undergoing Treatment With Gonado-Toxic Therapies.

The incidence of cancer in pre-pubertal boys has significantly increased and, it has been recognized that the gonado-toxic effect of the cancer treatments may lead to infertility. Here, we have evaluated the effects on porcine neonatal Sertoli cells (SCs) of three commonly used chemotherapy drugs; cisplatin, 4-Hydroperoxycyclophosphamide and doxorubicin. All three drugs induced a statistical reduction of 5-hydroxymethylcytosine in comparison with the control group, performed by Immunofluorescence Analysis. The gene and protein expression levels of GDNF, were significantly down-regulated after treatment to all three chemotherapy drugs comparison with the control group. Specifically, differences in the mRNA levels of GDNF were: 0,8200 ± 0,0440, 0,6400 ± 0,0140, 0,4400 ± 0,0130 fold change at 0.33, 1.66, and 3.33µM cisplatin concentrations, respectively (**p < 0.01 at 0.33 and 1.66 µM vs SCs and ***p < 0.001 at 3.33µM vs SCs); 0,6000 ± 0,0340, 0,4200 ± 0,0130 fold change at 50 and 100 µM of 4-Hydroperoxycyclophosphamide concentrations, respectively (**p < 0.01 at both these concentrations vs SCs); 0,7000 ± 0,0340, 0,6200 ± 0,0240, 0,4000 ± 0,0230 fold change at 0.1, 0.2 and 1 µM doxorubicin concentrations, respectively (**p < 0.01 at 0.1 and 0.2 µM vs SCs and ***p < 0.001 at 1 µM vs SCs). Differences in the protein expression levels of GDNF were: 0,7400 ± 0,0340, 0,2000 ± 0,0240, 0,0400 ± 0,0230 A.U. at 0.33, 1.66, and 3.33µM cisplatin concentrations, respectively (**p < 0.01 at both these concentrations vs SCs); 0,7300 ± 0,0340, 0,4000 ± 0,0130 A.U. at 50 and 100 µM of 4- Hydroperoxycyclophosphamide concentrations, respectively (**p < 0.01 at both these concentrations vs SCs); 0,6200 ± 0,0340, 0,4000 ± 0,0240, 0,3800 ± 0,0230 A.U. at 0.l, 0.2 and 1 µM doxorubicin concentrations, respectively (**p < 0.01 at 0.1 and 0.2 µM vs SCs and ***p < 0.001 at 1 µM vs SCs). Furthermore, we have demonstrated the protective effect of eicosapentaenoic acid on SCs only at the highest concentration of cisplatin, resulting in an increase in both gene and protein expression levels of GDNF (1,3400 ± 0,0280 fold change; **p < 0.01 vs SCs); and of AMH and inhibin B that were significantly recovered with values comparable to the control group. Results from this study, offers the opportunity to develop future therapeutic strategies for male fertility management, especially in pre-pubertal boys.

Accelerate Pheno™ system in sepsis by Gram-negative pathogens: four months of hospital experience.

This study reports our experience with the Accelerate PhenoTM system (ACC) to guide management of patients with sepsis by Gram-negative pathogens. A diagnostic workflow, based on pathogen and resistance genes detection or ACC testing, was applied to 33 patients. Clinical and microbiological data were recorded, and analysis of broad-spectrum agents sparing was performed. Antimicrobial susceptibility results by ACC were available for 28 of 33 patients (84.85%). Among 434 microorganism-antimicrobial combinations, categorical agreement was 97.93%, very major errors 0.23%, major errors 1.15%, and minor errors 0.69%. Time to report (mean ± SD) of ACC results was 27.14±6.90 h from sample collection, significantly shorter (p<0.001, Δ = 19.96 h, 95% CI: 24.71-15.22) than that of the standard method (47.10±11.92 h). A switch from empiric to targeted therapy was observed in 14 of 28 patients (50.0%), duration of empiric therapy was 37.73±19.87 h, with a saving of 5.45 piperacillin/tazobactam and 5.28 carbapenems prescribed daily doses. Considering patients in which de-escalation would have been theoretically feasible, 27.69 prescribed daily doses of piperacillin/tazobactam and 19.08 of carbapenems could had been spared, compared to standard methods. In conclusion, ACC could impact positively on the management of septic patients by Gram-negative pathogens.

A proposal for a comprehensive approach to infections across the surgical pathway.

Despite evidence supporting the effectiveness of best practices in infection prevention and management, many healthcare workers fail to implement them and evidence-based practices tend to be underused in routine practice. Prevention and management of infections across the surgical pathway should always focus on collaboration among all healthcare workers sharing knowledge of best practices. To clarify key issues in the prevention and management of infections across the surgical pathway, a multidisciplinary task force of experts convened in Ancona, Italy, on May 31, 2019, for a national meeting. This document represents the executive summary of the final statements approved by the expert panel.

The safety of nivolumab for the treatment of advanced non-small cell lung cancer.

INTRODUCTION: Immune checkpoint blockaders (ICBs) act by unbalancing the immune system, thus favoring the development of an immune-mediated antitumor effect. ICBs targeting the programmed cell death receptor-1 (PD-1) have recently been investigated in a number of advanced tumors, including non-small cell lung cancer (NSCLC). Nivolumab, a fully human IgG4 kappa directed against PD-1, has been the first ICB to be approved for second-line treatment of advanced NSCLC. Areas covered: In this review we focus on the clinical development of nivolumab for the treatment of advanced NSCLC, with an emphasis on its safety profile. In addition, we summarize the most common types of immune-related adverse events (irAEs) associated with nivolumab, mainly due to organ inflammation secondary to autoimmunity. Expert opinion: Nivolumab is the preferred treatment option for platinum-pretreated advanced NSCLC, having convincingly shown higher efficacy compared with standard docetaxel chemotherapy in phase III trials. The same trials showed far less incidence of either any grade and severe treatment-related AEs with nivolumab compared with chemotherapy. IrAEs associated with nivolumab are rarely severe in intensity, and often resolve with prompt management. Future studies will explore nivolumab in combination strategies with either platinum-based chemotherapy or other ICBs in treatment-naïve advanced NSCLC patients.

The strategic relevance of manufacturing technology: An overall quality concept to promote innovation preventing drug shortage.

Manufacturing is the bridge between research and patient: without product, there is no clinical outcome. Shortage has a variety of causes, in this paper we analyse only causes related to manufacturing technology and we use shortage as a paradigm highliting the relevance of Pharmaceutical Technology. Product and process complexity and capacity issues are the main challenge for the Pharmaceutical Industry Supply chain. Manufacturing Technology should be acknowledged as a R&D step and as a very important matter during University degree in Pharmacy and related disciplines, promoting collaboration between Academia and Industry, measured during HTA step and rewarded in terms of price and reimbursement. The above elements are not yet properly recognised, and manufacturing technology is taken in to consideration only when a shortage is in place. In a previous work, Panzitta et al. proposed to perform a full technology assessment at the Health Technological Assessment stage, evaluating three main technical aspects of a medicine: manufacturing process, physicochemical properties, and formulation characteristics. In this paper, we develop the concept of manufacturing appraisal, providing a technical overview of upcoming challenges, a risk based approach and an economic picture of shortage costs. We develop also an overall quality concept, not limited to GMP factors but broaden to all elements leading to a robust supply and promoting technical innovation.
